Question

Which ratio forms a proportion with 4/5?

2/3
4/10
16/20
16/25

Answer 1

16/20

Answer 2

16/20. Proportions have to be equal. 4/5 is equivalent to 16/20 because if you multiply it by 4/4 (which is the same thing as 1 so it doesn't change it at all), it becomes 16/20.

Answer 3

I don't think Tyndale cares how do actually do these so I just posted an answer.
