Oscar's age = 16
Sister's age = 12
Current year: 16 / 12
Simplest form: 4 / 3 ; both are divisible by 4.
2 years after: (16 + 2) / (12 + 2) = 18 / 14 ; add two years to both numbers.
Simplest form: of 18 / 14 is 9 / 7; both are divisible by 2.

Answer:
1/168
Step-by-step explanation:
First, solve for the numerator.
-5/7÷30
-5/7÷30/1
(use keep, change flip)
-5/7x1/30=-5/210
-5/210=-1/42
Now use keep change flip again
-1/42÷-4/1
-1/42*-1/4=1/168
