3 to the 8th is equal to 6561. 6.5 to the 12th is equal to 5688009063. They are not equal.

If you are referring to ratios:

The ratios can be re-written as fractions:

3 : 8 = 3/8

6.5 : 12 = 6.5/12

You now have two fractions to compare: make them equivalent fractions with the same denominator and compare the numerators:

3/8 = (3×3/(8×3) = 9/24

6.5/12 = (6.5×2)/(12×2) = 7/24

9 is not the same as 7, so 3/8 is not the same as 6.5/12, ie the ratio 3 : 8 is not equal to the ratio 6.5 : 12.

Multiplying both sides by 1.5 gives:

4.5 : 12
