Question

in a survey 3/10 people named blue as their favorite color. one out of the 5 named red. if 1,200 people were included in the survey, how many named blue or red as there favorite color

Answer 1

The integer for one out of 5 is 1/5.

Knowing this, we simply do

(3/10 + 1/5)*1200

(3/10 + 2/10) * 1200

5/10 * 1200

1/2 * 1200 = 600.

600 people named red and blue as their favorite color.
