500 people are asked to name their favorite color. The results of this survey are shown in the pie chart below:

Each sector of the pie chart makes an angle at the center. For example, the yellow sector makes an 18 degree angle, since 18 degrees is 5% of 360 degrees.

If we consider only the people who named a rainbow color (red, orange, yellow, green, blue, or purple), what percentage of those people preferred red?

Answer:

20%

Step-by-step explanation:

Method 1

Percentage of people who preferred red:

= 13%

Percentage of people who named a rainbow color:

= 13 % + 4% + 5% + 15% + 16% + 12%

= 65%

Percentage of people who preferred red from those who named a rainbow color:

= (13% ÷ 65%) × 100

= 20%

Method 2

Number of people who preferred red:

= 13% of 500

= 13% × 500

= 0.13 × 500

= 65

Percentage of people who named a rainbow color:

= 13 % + 4% + 5% + 15% + 16% + 12%

= 65%

Number of people who named a rainbow color:

= 65% of 500

= 65% × 500

= 0.65 × 500

= 325

Percentage of people who preferred red from those who named a rainbow color:

= (number who preferred red ÷ number named rainbow color) × 100

= (65 ÷ 325) × 100

= 20%
