Question

there were 4200 people at a concert and 1400 of these were female . what percentage were male

Answer 1

The number of male: 4200-1400 = 2800

So the percent of male = 2800/4200 = 2/3 =0.667 = 66.7%

Answer 2

Percentage of females = 1400/4200 * 100

                                      = 33.33%

⇒ Percentage of males = 100- 33.333 = 66.66%
