Ravi's bookshop received 60 storybooks. These were 25% of all the new books received. How many new books did the bookshop receive altogether?
Need a hint?
Since 25% is one quarter, find four equal groups of 60.
Worked answer
- 25% = 1/4.
- The 60 storybooks represent one of four equal parts.
- 60 × 4 = 240.
- The bookshop received 240 new books altogether.
Answer: 240 books

Calculation slip
Dividing 60 by 25 gives 2.4, but the percentage must first be written as a fraction of the whole.
