Answer:
2:1 or 2/1
Explanation:
the original ratio is 32:16 or 32/16
remember a ratio is like a fraction
as long as you divide both numbers by the same number, the ratio is still accurate
so in this case we will divide by 16 because it is the gcf
32 divided by 16 is 2
16 divided by 16 is 1
so the answer is 2:1 or 2/1
