A class of 30 students took a test. 60% passed. How many students failed?

A recipe uses flour and sugar in the ratio 5:2. If 350g of flour is used, how much sugar is needed?

Flour:Sugar = 5:2. If flour = 350g, one part = 350 ÷ 5 = 70g. Sugar = 2 × 70 = 140g.
A box has 24 chocolates. 1/3 are milk chocolate, 1/4 are dark chocolate, and the rest are white chocolate. How many are white chocolate?

A car's fuel tank holds 48 litres. It uses 6 litres per 100 km. How far can the car travel on a full tank?

In a sale, all prices are reduced by 1/5. A jacket originally costs £45. What is the sale price?

The mean of five numbers is 12. Four of the numbers are 10, 11, 13, and 15. What is the fifth number?
