Answer:

24 days

Explanation:

First, we need to determine the Lowest common multiplier(LCM) of both days.

Given that;

Ben exercise for 12 days ,

Isabel exercise for 8 days

Hence, the LCM of both days is

12 = 2 × 2 × 3

8 = 2 × 2 × 2

Therefore,

LCM = 2 × 2 × 2 × 3 = 24.

It will take both Ben and Isabel 24 days to exercise on the same day again
