Answer 4

Answer 5

how is already a fraction

Answer 6

It does not matter if Jim's number is a fraction or some ugly number.
You start with Jim's number. It goes up top. then you divide it by Jane's number

So, what is Jim's number ?

Answer 7

4 3/4

Answer 8

yes. and Jane's number is 3
so the problem is

4 3/4 divided by 3

the trick is to make it look like one of the choices.
any idea how to do this ?

Answer 9

4 3/4 is a mixed number. They are nasty to deal with. Can you change to an improper fraction ?

Answer 10

19/4

Answer 11

yes, now your problem is
19/4 divided by 3

you could write it like this
\[ \frac{ \frac{19}{4}}{3} \]
which is also a bit ugly

However, remember that dividing by 3 is the same as multiplying by 1/3
(Try to remember this idea)

so the problem can be written as
19/4 * 1/3

can you simplify ?

Answer 12

19/12
