How do you work this out?

Ben had a mean 82% for three exams.

If he scored 75% and 91% for two of the exams, what was his mark on the third exam?

If the average of 3 tests is 82% then 82 x 3 = 246... so 75 plus 91 equals 166... so the last exam has to equal 246 -166 or 80%

@Fungirlmmm It really is like learning another language. so many formulas and concepts you have to remember, it can be so confusing.

No you did great. I've been practising so much these numeracy questions, while I have gotten better, I still get confused at times. But just got to keep practising.
