1. ## 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

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 $\frac{2}{7}$ of the total then she gets $\frac{2}{7} \times 66.50$

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

Edit: corrected an error
