When asked to make a calculation and give the answer to one decimal place it is essential that you remember to do this or you will not gain the mark

Examiner Tips and Tricks
When giving an answer to one decimal point you will need to round the number up or down. Remember if the second digit after the decimal point is 4 or less you round down. If the second digit is 5 or more you round up. For example,
23.3714 would become 23.4 because the second digit after the decimal point is 7
23.3314 would become 23.3 because the second digit after the decimal point is 3
