Question

Tim picked up 20% of the books in the room. If he picked up 8 books, how many were in the room? Explain your answer please, I will mark it brainly! :)

Answer 1

Answer: 40 books

Step-by-step explanation: 20%=8 Books

100 divided by 20 = 5

8 x 5 = 40

Answer 2

Divide 20% by 100 to obtain its decimal form. Dividing 20% by 100 equals 0.2. Set up an equation as 0.2x = 8 which means 20% of x equals 8. Solve the equation by dividing each side by 0.2, Dividing 0.2 from each side results in x=40 Eight is 20% of 40
So there were 40 books in the room and he took 8 making the books 20% less.
