The normal price of a television is £1200. It is reduced to £970. Work out the percentage reduction. Give your answer to 1 decimal place.

First we calculate the difference between the original price and the new price. This is £1200 - £970 = £230. We now divide this difference by the original price, and multiply it by 100 to find the percentage reduction. If we type 230/1200 *100 into a calculator, we get 19.16666667 (or something similar, depending on how many decimal places our calculator gives us!). We only want our answer to one decimal place. We look at the digit in the second decimal place, which is 6. Since this is greater than or equal to 5, we round up the first decimal place, so the answer is 19.2%.
