Work out 17% of 54 - OCR - GCSE Maths - Question 6 - 2017 - Paper 1

To find 17% of a number, we can use the formula:

ext{Percentage} = rac{ ext{Percentage Rate}}{100} imes ext{Base Number}

Here, the Percentage Rate is 17 and the Base Number is 54. Therefore:

17 ext{ ext{%}} = rac{17}{100} imes 54

Calculating this gives:

$$= 0.17 imes 54 = 9.18$$

Rounding this to 1 decimal place gives us 9.2.
