Question

In a survey, one out of five people named blue as their favorite color. Three out of ten named red. If 1,100 people were included in the survey, how many named blue or red as their favorite color

Answer 1

1/5 = x/1100                                                    

5x = 1100
x = 1100 ÷ 5
x = 220

So 220 people named blue as fav.

3/10 = x/1100

3x = 1100
x = 1100 ÷ 3
x = 366.6666.... = 367

So 367 people chose red
