Christian read 1/4 book every 2/3 per week. how many books does he read per week

Christian reads 3/8th of a book a week.

Step-by-step explanation:

In order to find this amount, we need to multiply both numbers by a factor that will get the weeks to equal 1. In order to get 2/3 to equal 1, we need to multiply by 3/2 (the reciprocal). Now knowing this, we can multiply the number of books by that same fraction to get the amount of books in one week.

1/4 * 3/2 = 3/8

3/8th is your answer.

He reads 3/8th books per week.
