Answer:
it's 512
Step-by-step explanation:
I think it’s 5 but don’t get mad if it’s wrong
21= 1,3,7,21
30= 1,2,3,5,6,10,15,30
common factors= 1,3
These ratios are not proportional.
Explanation:
If the ratio 8:32 were simplified, it would equal 1:4 because they can both be divided by 8. But since 16 x 4 does not equal 72, they cannot be divided by 4 to make a simplified ratio such as the first example.
Hope I helped, and good luck!
