Fraction problems

Question

A theme park makes £300 profit every day. If 1/3 of the profit comes from entry fees, 1/6 comes from selling food and 2/5 comes from selling gifts  how much money is made from everything else  each day?

 

Answer 1

1/3 + 1/6 + 2/5 = 10/30 + 5/30 + 12/30 = 27/30 = 9/10

 

So, the other 1/10 is the rest.

 

(1/10)300 = 30
