i dont get it either... it was a question 4 my revision...

i think ur meant 2 do something with the 2 ans... (divide them... but it still doesnt get the correct ans... so i dont no how 2 work it out...) - Dec 1st 2009, 11:23 AMRaoh
well, $\displaystyle \frac{3}{5}$ is only what's left from joe's pizza(Rofl), $\displaystyle \left (1-\frac{2}{5} \right )=\frac{3}{5}$.

Hello, janvi anish!

Quote:

Joe has eaten $\displaystyle \frac{2}{5}$ of a pizza and Sue has eaten $\displaystyle \frac{1}{9}$ of a pizza.

How many more times has Joe eaten a pizza more than Sue?

The answer is $\displaystyle \frac{3}{5}.$ . . . . . This is wrong!

We have: .$\displaystyle \frac{\:\dfrac{2}{5}\:}{\dfrac{1}{9}} \;=\;\frac{2}{5}\cdot\frac{9}{1} \:=\:\frac{18}{5}$

Joe has eaten $\displaystyle 3.6$ times as much pizza as Sue ate.

yes this is what we get also but on the answer it is saying 3/5 that is why we do not get it!!we have tried it many ways and get the same answer as you do but we think it is something to do with 'how many more times'

yes thanks but again we have another one similar...

joe has eaten 4/5 of a pizza, jane 1/8 how many more times has joe eaten a pizza than jane..this says that the answer is 2/5...but again i do not get it.....

i am sure it is in the wording somewhere.... - Dec 1st 2009, 01:12 PMPaul46
