On the first day, Luis read half of the book. on the second day, he read 3/8 more and 40 pages remain. How many pages were their in the book?

Sagot :

40÷5 Because there are 5 shares in the 40 pages that is left. 40÷5=8 Each 1/8 of a half has 8 pages, so 8/8 is 8×8 Because an 1/2 is an 8/8 so 8×8=64 1/2+1/2=The whole book=64+64=128 So, there is a total of 128 pages in that whole book.
