Hey there!
First, we need to find how many books he read EACH week. To do that, all we need to do is divide 6 by 4
6 ÷ 4 = 1.5
So, he read 1.5 books each week. Now, to find how many books he would read in 7 weeks, all we have to do is multiply his weekly rate (1.5) by 7
1.5 x 7 = 10.5
Therefore, he will read 10.5 books in 7 weeks
Hope this helps you!
God bless ❤️
