Question

Select three ratios that are equivalent to 8:5 Choose 3 answers:

Answer 1

A, C, D are the right answers since both sides are divisible by 5 and 8, respectively.

Answer 2

The correct answers are A, C, and D. Here’s why:

16 and 10 are both divisible by 2. 2*8=16 and 2*5=10. So this one works.

48 and 30 are both divisible by 6. 6*8=48 and 6*5=30. So this one works.

32 and 20 are both divisible by 4. 4*8=32 and 4*5=20. So this one works.

Another way to think about it is if you put them as fractions and reduced them down to their simplest form, they would form the fraction 8/5.

16/10: divide each by 2 to get 8/5.

48/30: divide each by 6 to get 8/5.

32/20: divide each by 4 to get 8/5.
