Question

Every 6 months, Andrea reads 10 novels. If she continues to read this many novels for every 6-month period, how many months will it take for her to read 15 novels?

Answer 1

9

Answer 2

9 months

Answer 3

This is how you do it.

6 months = 10 novels

You want to find out how many months it takes for her to read 15 novels.

Half of 6 months = 3 months, and half of 10 novels = 5 novels.

So this means:

3 months = 5 novels

And we already have

6 months = 10 novels

We can add these together to get:

9 months = 15 novels
