He only ate $\frac{2}{5}$ of a pizza,not all of it.

3. yes... joe only ate 2/5 of the pizza... not all of it...

yes,but you're asking "how many more times has joe eaten a pizza (a whole one) more than sue",how's that possible?
(or probably i haven't understood what you meant in your question)

5. 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...)

6. well, $\frac{3}{5}$ is only what's left from joe's pizza, $\left (1-\frac{2}{5} \right )=\frac{3}{5}$.

7. Hello, janvi anish!

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

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

The answer is $\frac{3}{5}.$ . . . . . This is wrong!
How does $\frac{2}{5}$ compare to $\frac{1}{9}$ ?

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

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

8. 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'

With the info you gave us Soroban's answer is correct. Answers in the back of the book aren't always correct!

10. 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....

11. I was going to say 13/45, the way i got it was 5*9 = 45, 9*2=18, 5*1 =5, 18-5 =13/45 , but reading the question properly it's 18/5= 3.6 like someone mentioned

$\frac{\frac{4}{5}}{\frac{1}{8}}= \frac{4}{5}\times 8= \frac{32}{5}$
Therefore Joe has eaten 6,4 times as much pizza as Jane ate.
