Answer 2

I think your right... but let @jim_thompson5910 check

Answer 3

Just incase... lol

Answer 4

16/200 = 0.08
2/25 = 0.08

so that shows 16/200 = 2/25. It looks good

Answer 5

Yay good job @Ms-Brains

Answer 6

Thanks buddy! :) What about this one guys?

Answer 7

I'm thinking either A or B

Answer 8

What we want: the goal is to get `m/n` on one side


9n = 3m


9n/n = 3m/n ... divide both sides by n


9 = 3m/n


9*(1/3) = (3m/n)*(1/3) ... multiply both sides by 1/3


9/3 = m/n


m/n = 9/3


m/n = 3/1

Answer 9

Oh, okay. Thanks! What about this one?

Answer 10

or you can do it this way

9n = 3m


9n/3 = 3m/3 ... divide both sides by 3


3n = 1m


3n = m


3n/n = m/n ... divide both sides by n


3/1 = m/n


m/n = 3/1

Answer 11

Awesome. cx I posted a new attached file too. I'll re-post it

Answer 12

whenever it comes to ratios, ask yourself "do the pieces have any factors in common?"

If the answer is "yes", then you can divide each piece by that factor to reduce the ratio. You keep doing this until the only factor they have in common is 1

Answer 13

Okay. :) So it isn't A?

Answer 14

going from `6y:8y` to `6:8` you divided each piece by the shared factor `y`. But is there more dividing left to be done?

Answer 15

do 6 and 8 have anything in common?

Answer 16

Uhh..no?

Answer 17

you sure? list out the factors of each

Answer 18

You know what, let's just move on to the next problem, I need to figure them out quick. I'll do this one later..

Answer 19

factors of 6: 1,2,3,6
factors of 8: 1,2,4,8

Answer 20

They have 1, 2, in common?

Answer 21

yes divide each term (6 and 8) by that greatest common factor 2 to fully reduce the ratio

Answer 22

3:4 is correct?

Answer 23

yes since
6/2 = 3
8/2 = 4

Answer 24

Awesome!

Answer 25

What about this one @jim_thompson5910

Answer 26

That one is correct

Answer 27

Okay this is right. Because you divide each side by 10.

Answer 28

BUT

Answer 29

Confirm with someone else lol @Ms-Brains

Answer 30

Also.. @Ms-Brains It is better to make another post. You can get more help.

Answer 31

Thanks guys. last one!

Answer 32

6/5 is correct

Answer 33

Thanks guys! 5/5 :) I'm off to take my quiz now.
