Where is part ll ? 10/7/2013 11:18:53 am
2:5 is different from 5:2 because 2 boys are being compared to 5 girls and 5:2 is 5 girls being compared to 2 boys. 10/7/2013 11:27:59 am
A unit rate can be expressed by saying for example:

2:5 is different to 5:2, because in the first one is comparing boys to girls and the second one is comparing girls to boys. a unit rate is where you show what your measuering and how many of something per something. example: $5 per toy.

Helooooo everybody
Ms. L. Scott

Hello Robert, did you figure out what the answer was for question number 2?
Robert Blue
10/7/2013 10:19:43 am
the difference between 5:2 and 2:5 is that it shows a different fraction like 5/2 or 2 and 1/2 and 2/5
Ms. L. Scott

We are working with ratios not fractions. Please look at your INB for notes.

1. because your saying their is 2 boys compared to 5 girls and your saing their is 5 girls compared to 2 boys
olivia green

we have to wright this on a serperate sheet of paper?

No you should be answering these questions on this page.

The ratio of 2 boys : 5 girls is different because they switched the numbers around. You would know if an answer is a unit rate because it would look like this ______Price____. A ratio would look like a fraction,_ to _, or when Number
Ms. L. Scott
10/7/2013 10:49:25 am
Your unit rate is missing some information. Please make sure to review your INB.
David Coffman
10/7/2013 11:58:52 am
The reason the two ratios, 2boys:5girls and 5girls:2boys, are different is they are reversed
David Coffman
10/7/2013 12:00:29 pm
I mean the number on the bottom like denominator can only be 1 to be a unit rate also
Robert Blue
10/7/2013 10:21:43 am
I think mackenzie is right that what i say too. 10/7/2013 10:26:36 am
1. Because 2 boys is being compared to 5 girls.
Ms. L. Scott
10/7/2013 10:54:44 am
$11.00 for 22 bananas is not a unit rate. Think about the word unit!!!
Court Green
10/7/2013 01:08:08 pm
I agree. I made my method like that.
Robert Blue
10/7/2013 10:30:25 am
you can tell what is a unit rate is there is 1 at the bottom like 30/3 turns into 10/1, but i didn't have to give that example
Ms. L. Scott
10/7/2013 11:14:02 am
That is a great example!!

2 to 5 is different from 5 to 2 because it expreses different comparings. There could be compare boys to girls and the difference is 5 boys to 2 girls or 2 boys to 5 girls.
Elizabeth Green
10/7/2013 10:31:28 am
1) is 2 boys compared to 5 girls and their is 5 girls compared to 2 boys.
Alekha Green

This is green homework right?
Ms. L. Scott
10/7/2013 11:43:52 am
The order matters because your question depends on it. For instance if I asked for boys then why would you tell me about girls. Therefore if they asked for boys first that's what you discuss. Also in a real world sceniro if you were planning a party and the ratio was 2 girls to 5 boys, would you make 5 goodie bags for the girls at the party? Think about who would not get a party bag based on your incorret ratio.
elizabeth blue
10/7/2013 10:46:00 am
1) because the first one is comparing boys to girls and the second one is comparing girls to boys so the order is different
Sophie Yellow
10/7/2013 10:56:25 am
1) 2 to 5 is different from 5 to 2 because in the first one, it is 2 compared to 5, not 5 compared to 2. 10/7/2013 11:38:25 am
I agree with you Sophie because I use "for" when using unit rates.
Dylan Green
10/7/2013 11:02:20 am
Are we supposed to be doing this on a sheet of paper?
Ms. L. Scott
10/7/2013 11:20:53 am
No you should be posting your answer to the board & then responding to 3 other class mates.
olivia green

i dont know
Zoe Blue

1. 2 boys:5 girls is 2/5 and 5 girls:2 boys is 5/2 ( They are different fractions.)
David Coffman
10/7/2013 12:03:51 pm
I would have to all but concur to agree
Josie Green
10/7/2013 11:14:07 am
The ratio of 2 boys to 5 girls is different form 5 girls to 2 boys because the ratios are switched to represent boys to girls or girls to boys. I can tell something is a unit rate because it always has a 1 as the denominator which shows how much something is for the amount of 1
Ms. L. Scott
10/7/2013 11:34:55 am
Great explanation of unit rate!!!
Oliviayellow
10/7/2013 11:27:26 am
1.) The ratio 2 to 5 is different from 5 to 2 because the ratios are opposites
olivia green
10/7/2013 11:27:36 am
1) you are comparing different things to each other
Court Green
10/7/2013 01:06:43 pm
Same here.
Ms. L. Scott
10/7/2013 11:45:55 am
Please give a specific answer for question number 1. What two things are you comparing and in what order?
Connor Green
10/7/2013 11:42:52 am
1 the difference between 2:5 and 5:2 in that 2:5 is telling how many boys to girls and 5:2 is telling how many girls to boys
Green Rahsan
10/7/2013 11:49:35 am
The difference is that 2:5 and 5:2 is that 2:5 your comparing 2 boys to 5 girls.5:2 your comparing 5 girls to 2 boys.Compating boys to girls and girls to boys are different
ellie yellow
10/7/2013 11:54:17 am
1. 2to5 is different from 5to2 because 2 to 5 would be comparing 2 boys and 5 girls and 5 to 2 is comparing 5 girls to 2 boys
remy blue
10/7/2013 11:54:30 am
the difference between 2;5 and 5;2 is that there switched so you would be comparing 2 boys to 5 girls, or 5 girls to 2 boys.alway
jalen green
10/7/2013 11:56:21 am
it is diffrent because instead of saying boys to girls you are sayng girls to boys
jalen green
10/7/2013 11:59:19 am
say if theres 7.89 for 5 and they ask you how much for one then they want you to find the unit rate
remy blue
10/7/2013 12:02:18 pm
a unit rate is expressed by
zeren green
10/7/2013 12:10:58 pm
It is different because instead of you comparing boys to girls you are comparing girls to boys 10/7/2013 12:12:54 pm
1. 2:5 is different from 5 girls:2 boys is because the first one is 2 boys to 5 girls so you would put 2:5 but 5 girls to 2 boys is 5:2 you have to put it in the order it says 2.like say you had 4/2 the unit rate would be 2 because you would have to divide 4 and 2 by 2
zeren green
10/7/2013 12:13:31 pm
You can tell whether it is a unit rate cause it is compared to 1
Noah Green
10/7/2013 12:16:41 pm
1. You are comparing 2 boys to every 5 girls. Then comparing 5 girls to 2 boys.
martha yellow
10/7/2013 12:41:02 pm
#1. They are different because if you had 2 boys for every 5 girls, it wouldn't be the same as having 5 girls for every 2 boys. The order is really important in this.
gidblue
10/7/2013 12:58:59 pm
1)The difference is because if you are asking 2to5it would be 2 boys to 5 girls. Therefore if you ask 5 girls to 2 boy. There is a big difference.
Isaac yellow
10/7/2013 01:01:12 pm
2:5 is different from 5:2 because 2 boys is being compared to 5 girls which is not the same as 5 girls being compared to 2 boys. Another way of saying it is if you had 2 boys for every 5 girls, or 5 girls for every 2 boys.
Cole Blue
10/7/2013 01:03:41 pm
1.Because you would be comparing two different parts: 5 to 2 and 2 to 5.
isaac yellow
10/7/2013 01:05:51 pm
You can tell if a number(s) is a unit rate by if there is one unit. Ex:
Court Green
10/7/2013 01:11:11 pm
2:5 is different from 5:2 because you are comparing two different numbers, wielding a different result.
hanna yellow
10/7/2013 01:20:29 pm
1) 2:5 is 2 boys to 5 girls and 5:2 is comparing 5 girls to 2 boys
Jackson yellow
10/7/2013 01:47:40 pm
1.It is different because you are comparing 2 boys to 5 girls then your comparing 5 girls to 2 boys.
gianna blue
10/7/2013 01:53:24 pm
1. tre ratios are different because they both are saying two different ratios(one is boys to girls and the other is girls to boys)
Gute Green
10/7/2013 03:11:12 pm
2:5 is 2 girls to 5 boys and 5:2 is boys to girls
Gute Green
10/7/2013 03:13:13 pm
you can tell its not a unit rate because unit rates find the price for a single item
sebastian green
10/7/2013 03:25:00 pm
1.because it is swiched
Zoe Yellow
10/8/2013 01:48:45 am
If it says to figure 2 boys to 5 girls, then 5:2 is wrong because it needs to be in the order written. Comments are closed.
