55% of Toby's friends are boys and the rest are girls. If he has 33 friends who are boys, how many friends does he have who are girls?
How many friends does Toby have? ** Toby has 60 friends because 33 / .55 = <<33/.55=60>>60
How many friends are girls? ** 45% of his friends are girls because 100 - 55 = <<100-55=45>>45
How many friends are girls? ** He has 27 friends who are girls because 60 x .45 = <<27=27>>27
