Yeah, that's something I have realised about maths in the past couple of months of doing GCSE maths. (I've often come to the same answer even though I didn't follow the solution as shown in the answer sheet.)

The trick to this kind of question is seeing what you can work out based on what you are told. You are told the fraction of people that chose two out of three meals, so you can work out the third fraction of people as whatever fraction is remaining.

An easier version of the question would be:

There is an amateur football match.

All of the fans present support either the home team or the away team.

7/10 of the fans support the home team.

30 fans support the away team.

How many fans are there in total?


If 7/10 support the home team, then 3/10 must support the away team. If 30 people are three tenths, then the total number of people is 100.

It's the same logic in your question, just with harder numbers.


This is helping. Thank you.

I just wanted to reiterate this point because I think if you go into this sort of question thinking that you need a calculator and that the calculator will be able to give you the answer probably makes it more difficult. They want to know whether you understand fractions as a principle and can apply that to figure out the question, the calculator is just a tool you may want to use to help you with the arithmetic once you figure out how to solve the problem.

No wonder Trump want to stop the count.

I’ve forgotten a lot of basic maths rules so if my kids ask me what to do, I’ll ask Grcade. :slol:

Maths can get to the strawberry float.

:| Awful.

Turns out I did the hardest paper first (it had the shortest deadline ffs!) :fp: The other two may (or may not) have helped me get a better handle on what I was being asked in the paper I did first. strawberry floating SIGH.

Saw a video online somewhere about how high you could count on your fingers and taking into account knuckles and stuff it was something ludicrous like 60,000.

I mean, presumably that wouldn't actually help you keep track of the numbers though right? Just a way of saying the numbers?
