Question

How do you simplify `4 1/2 div 1 4/5`?

Answer 1

`2 1/2`

Explanation:

Convert the mixed numbers into improper fractions

`4 1/2=9/2` and `1 4/5=9/5`

So `4 1/2-:1 4/5`=`9/2-:9/5`

When dividing fractions we invert the second fraction and multiply

`=> 9/2-:9/5 =9/2 xx 5/9`= `45/18` =`5/2 =2 1/2`
