Question

Are the ratios 8/12 and 10/25 proportional? (Explain in steps)

Answer 1

Okay, so first, lets determine whether or not these are equivalent, which will lead us to our answer. 

8/12 < lets simplify this

8/4 = 2
12/4 = 3

8/12 = 2/3

10/25

10/5 = 2
25/5 = 5

10/25 = 2/5

2/5 ≠ 2/3

These ratios are not proportional. 

Answer 2

8/12
= (8/4) / (12/4)
= 2/3

10/25
= (10/5) / (25/5)
= 2/5

Because 2/3 ≠ 2/5, 8/12 and 10/25 are not proportional~
