Answer 2

18%

Explanation:

Iliana's math grade increased from 65 to 86.

So, the percentage increase in the her math grade will be
`((86-65) * 100)/(65) = 32.31`% (Approximate)

Now, Fiona's math grade increased from 70 to 80.

Hence, the percentage increase in her math grade will be
`((80-70)* 100)/(70) =14.28`% (Approximate)

So, the difference rounded to the nearest whole number between the approximate percent increases in math grades will be

(32.31 - 14.28) ≈ 18%

So, it is eighteen percent. (Answer)
