Thread: Ratio question confusing.

OK so I got this question which I can't do.

It's from a GCSE Maths book.

Danny and Melissa work in a cafe, Danny works 5 days a week but Melissa works 2 days a week. To be fair they agree to share their tips in the ratio of the numbers of days of they work.

A: In what ratio do they share their tips
B: What fraction of tips should Danny receive?
C: If the tips in one week came to £66.50 how much did Melissa receive
D: The following weeks the tips came to £84 How much did Danny receive
E: One week Danny received £25 in tips how much did Melissa receive.

OK I know the answer to A is 7 and answer to B is 5/7 but I do not know the rest. I don't know the method to work them out

Hope someone can help.

Thanks

your answer to A should be a ratio. the answer is "5:2".

Your answer to B is correct.

for part (c), what fraction of the tips does melissa get? multiply this by the total tip amount to get the size of her share.

part (d) is a similar method to part (c).

part (e): the ratio is "5:2". you can multiply both sides of the ratio by any number, so this is the same as "2.5:1" which is the same as "25:10". now can you answer?

I still don't understand part C what numbers I multiply by?

if melissa gets of the total then she gets

PS: You will often find that "of" means "times" in maths problems.

Edit: corrected an error
