To make

you need

more. So, the second fraction is

Rewrite

as the equivalent whole number 5

Rewrite

as the equivalent whole number 5

So,

which is the mixed number

You can also use division to write

as a mixed number. Earlier, you found the greatest multiple of 4 within 21, which gave you

You then found the remaining difference between

and

which gave you

This is the same as finding the quotient and remainder when dividing 21 by 4.
