A. 5/36




B. 5/13




C. 5/12




D. 8/13

Answer 1

3x5=?
4x9=?

Answer 2

15 and 36

Answer 3

so what divides into both 15 and 36?

Answer 4

2

Answer 5

well 15 is an odd number, so 2 can't divide into 15 without having a remainder

Answer 6

1

Answer 7

okay, write out your 3 times table (up to 12x3), and tell me if both 15 and 36 are in it?

Answer 8

they are not both in it

Answer 9

write your 3x table out on here for me, so i can see where you are doing wrong :)

Answer 10

3 x 1=3 3 x 2 =6 3 x 3=9 3 x 4=12 3 x 5=15 3 x 6= 18 3 x 7= 21 3 x 8 =24 3 x 9=27 3 x 10= 30 3 x 11 =33 3 x 12= 36

Answer 11

i see where i went wrong

Answer 12

good :)

Answer 13

so it s 3

Answer 14

so to put a fraction in its lowest terms, the goal is to find a common number that divides them both, so we have:
\[\frac{ 3 }{ 4 }*\frac{ 5 }{ 9 }=\frac{ 15 }{ 36 }\]
so if we divide the top and bottom numbers by '3' - becuase we know that they both divide, what do we get?

(yes it is 3) :)

Answer 15

so we have \[\frac{ 15 \div 3 }{ 36\div3 }= \frac{ ? }{ ? }\]

Answer 16

I dun even know the answer, but I'd be happy for someone to mark me as Best Response for doing Absolutely Nothing!!

Answer 17

oh wait, this question is easy

Answer 18

5 and 4

Answer 19

top one is right,
15/3=5
but 36/3 does not equal 4...look at the table you wrote about

Answer 20

36 is bigger than 15 so the answer has to be bigger than 5

Answer 21

12

Answer 22

yes!! so if we have
15/3=5 on the top
and 36/3=12 on the bottom
what fraction do we have?

Answer 23

5/12

Answer 24

yes!! that is correct!

Answer 25
