Wait, could you help me with one more thing? If so do you want me to open another question or can we just do it here?

Answer 21

sure :) we can do it here...

Answer 22

Okay so the question says Match each pair of equivalent ratios... okay so it says 10/25 would it be 2:5 because 5 can go into ten 2 times and because 5 can go into 25 five times.. is this correct?

Answer 23

yes thats correct !

Answer 24

okay and the next one says 6 to 8, would it be 3/4?

Answer 25

correct :D looks these are too easy for you to solve :)

Answer 26

haha, well the next one i dont understand really :p

Answer 27

lets see

Answer 28

it says 13/20 and the answers are 6 to 16 and 65%, just from looking at it i dont think 6/16 can do anything with 13/20 so i think it would be 65% but could you explain it to me?

Answer 29

you're right ! its 65 %

Answer 30

But why is it 65%

Answer 31

13 is 65% of 20

Answer 32

lets see this from reverse :-

65% = ?

Answer 33

65% = 65/100

Answer 34

simplify

Answer 35

0.65?

Answer 36

leave it in fraction form

Answer 37

65% = 65/100

5 goes in 65 how many times ?

Answer 38

5 goes in 100 how many times ?

Answer 39

13 times and 5 goes into 100 20 times so it would be 13/20 in simplest form

Answer 40

Is that right! :D

Answer 41

thats it !

Answer 42

Yay!! :D thank you so much!!!!

Answer 43

good job !! yw :)

Answer 44

you can also do it in direct way like below :-

\(\frac{13}{20} = \frac{13}{20}\times 100 \% \)

\( = ?\)
