Sam read 60 pages, which is 3 4 of the book. How many pages are there in the book?

Step-by-step explanation:

x=80

80 pages

Step-by-step explanation:

Because 60 pages is 3/4 of the total number of pages, you can create the equation:

60 = 3/4x, with x being the total number of pages

To solve, divide the number on the left (60) by the numerator (3)

60/3 = 20

3/4x / 3 = 1/4x

20 = 1/4x

Then, multiply both sides by 4

20*4 = 80

1/4x*4 = x

80 = x

Thus, 80 is the total number of pages in the book
