Question

How to divide mixed numbers

Answer 1

convert them into improper fractions (form a/b) and then divide them by inverting the secodn fraction and multiply them

Answer 2

You can of course use a calculator, but if you can't, just put them into improper fractions. So 2 3/4 as an example would be 11/4. So if you had 2 3/4 divided by 4 1/2, you'd have (11/4)/(9/2).
When you divide fractions, you can multiply by the reciprocal. So you'd go (11/4)•(2/9)=22/36=
11/18
