Question

The shaded area on the grid represents the part of the rectangular wall that was painted. Each small square on the wall has the same dimensions. Which percentage of the wall was painted?

Answer 1

The correct answer is 60%

Step-by-step explanation:

A percentage represents a proportion of a total or 100% by using a number from 1 to 100. In this context, the first step is to count how many squares there are and how many were painted. This leads to the following results:

40 squares in total

24 painted squares

Knowing these two details it is possible to calculate the percentage. Follow this process:

- Write the values

40 squares = 100 % or total

24 squares = x (the value that needs to be found)

- Cross multiply to create an equation and solve this equation

40 x = 2400

x = 2400 ÷ 40

x = 60

The percentage that was painted was 60%
