Answer: 800

Step-by-step explanation:

If 40 people is 5%, we can set up a proportion to find the total number of readers.

40/x = 5/100

Cross-multiply to solve.

5x = 4000

Divide by 5 on each side to isolate the variable.

x = 800

The newspaper has 800 readers.

Answer:

800 people

Step-by-step explanation:

100% is made up of 5% times 20 (20x5=100) so you multiply the 40 people in 5% by 20 and get 800
