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?
Toby has 60 friends because 33 / .55 = <<33/.55=60>>60
45% of his friends are girls because 100 - 55 = <<100-55=45>>45
He has 27 friends who are girls because 60 x .45 = <<27=27>>27
#### 27
