The ratio of CD:GH is 2:3. What is the length, in meters, of side EH on the photocopied image?

Answer 1

@TheSmartOne

Answer 2

\(\sf\frac{2}{3} = \frac{8}{EH}\)

Cross multiply, do you know how to do that?

Answer 3

cross multiplying, you'd do 3*8 and 2*EH?

Answer 4

so 3*8 = 24
and how do you do 2*EH? @TheSmartOne

Answer 5

we eneed to solve for EH

so you got

24 = 2*EH

divide by 2 on both sides

EH = ??

and that's your answer :D

Answer 6

24/2 = 12
so EH = 12?

Answer 7

And that's your answer :D

Thanks!
