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.
