Answer 13

Always happy to help :)
Do you mean 21/x and 7/10 & x/50 and 16/25?

Answer 14

it says 21 to x and 7 to 10 so im sure thats the same

Answer 15

okay

Answer 16

the other is listed the same way

Answer 17

Cross-Multiply:
21/x and 7/10
21(10)=7x

x/50 and 16/25
25x=50(16)

Answer 18

i think somethings wrong ;o

Answer 19

or im reading it wrong

Answer 20

2:x = 12:18 for what value of x?

2/x = 12/18

if we cross multiply, 2*18 = 12*x
36 = 12*x
x = 3

2:3 = 12:18

as a check, multiply the ratio on the left by 6 and verify that it equals the one on the right.
2*6:3*6 = 12:18
12:18 = 12:18

(multiplied by 6 because that's the ratio 12:2, just checking that the denominator of our answer also is in the ratio 12:2)

Answer 21

21:x and 7:10

21*10 = 7*x
210 = 7x
30 = x

x/50 as 16/25

x*25 = 50*16
x = 50*16/25 = 2*16 = 32

Answer 22

;o whoaa

Answer 23

ohh 30 i got 30

Answer 24

do you still think something is wrong?
