Answer:
7^-12 or 1/7^12
Step-by-step explanation:
To divide exponents with the same base, subtract the second exponent from the first.
So:
7^-5/7^7 = 7^-5-7 = 7^-12
You can also write 7^-12 as 1/7^12.
Let these two ages be i and m. Then (1/3)m = 2i, which becomes m = 6i when we multiply both sides by 3.
Ratio:
M's age 6i
---------- = ------ = 6
I's age i
M is 6 times older than Ivan.
<span>The ratio of M's age to Ivan's is 6:1, or just 6.
