Question

Select all ratios equivalent to 5:4.

Answer 1

Select all ratios equivalent to 5:4.

Answer 2

Ratios equivalent to 5:4 are any pair obtained by multiplying both terms by the same nonzero number k. So for k = 2, 3, 4, 5, ... you get:

- 10:8
- 15:12
- 20:16
- 25:20
- 30:24
- 50:40
- 125:100
- …and so on.

As a fraction, 5:4 = 5/4 = 1.25, so any ratio equal to 1.25 (for example 1.25:1) is also equivalent. Note 4:5 is not equivalent (it’s the reciprocal).

If you have a list of choices, paste them and I’ll mark which ones are equivalent.
