What percent is the shaded portion of the entire diagram?

Question

A bar diagram with 9 shaded squares and 11 unshaded squares.
9%
40%
45%
90%

Answer 1

To find the percent of the shaded portion of the entire diagram, you need to determine the total number of squares and then calculate the proportion that is shaded.

1. Calculate the total number of squares:

   • Shaded squares: 9
   • Unshaded squares: 11
   • Total squares = 9 + 11 = 20

2. Calculate the percent that is shaded:

   • Percent shaded = (Number of shaded squares / Total squares) × 100
   • Percent shaded = (9 / 20) × 100 = 45%

Therefore, the shaded portion of the entire diagram is 45%.
