In a recent survey of 700 people, 15% said that red was their favorite color. How many people said that red was their favorite color?

Find out 15% of 700 through multiplying 700 by the decimal equivalent of 15% (0.15); 700 × 0.15 = 105; 105 people said in which red is their favorite color. Another way of looking at this problem is to recall which 15% means "15 out of 100." Since 700 is 7 times 100, multiply 15 by 7 to ?nd out the number of people out of 700 who said red was their favorite color; 15 × 7 = 105.
