Question

Which pair of ratios forms a proportion?

10 over 16. and 5 over 32.

10 over 22. and 5 over 11.

14 over 8. and 7 over 16.

8 over 44. and 16 over 22.

Answer 1

For there to be a proportion, if you place the fractions together and simplify each side, they should be equal, for example:
1) 10/16 = 5/32?
5/8 =/=5/32

2)10/22 = 5/11?
5/11=5/11 which is true so that's the proportion
