A soccer match was attended by 450 spectators. One third of them were men, two fifth of them were women and one tenth of them were boys. How many girls attended the soccer match?

Answer 1

One third of them were men:

1 / 3 * 450 = 450 / 3 = 150 men

Two fifth of them were women:

2 / 5 * 450 = 2 * 450 / 5 = 900 / 5 = 180 women

One tenth of them were boys:

1 / 10 = 450 / 10 = 45 boys

150 + 180 + 45 = 375

450 - 375 = 75 girls
