Question

If £1 is equal to 99.72 rupees and the post office only has 500 rupee papers how much can I change out of £450

Answer 1

£1 = 99.72 rupees -> £450 = 44874 rupees.

As the post office only has 500 rupee papers, once we calculate out the result, we have to round down to the nearest whole number.

The amount of rupee papers we can change out is : 44874 : 500 = 89.748 (papers)
We round down to 89 papers.
