Question

On a soccer team, 8 out of 19 players surveyed say they had two or more siblings. The league has 570 players. Which is the best prediction of the number of players in the league that have two or more siblings?

A.330

B.240

C.30

D.11

Answer 1

Since we know that 8 out of 19 players have two or more siblings, we can write the ratio as 8/19. Now to use that for the whole team, we will cross multiply:

8/19 and x/570, to find x. so 8*570 = 19x == 4560 = 19x, x = 240.

So (B) 240 players on the team have two or more siblings.
