Question

How do you divide `\frac { 11} { 18} \div 4\frac { 1} { 2}`?

Answer 1

See explanation.

Explanation:

If an expression contains mixed numbers and multiplication or division you have to change the mixed number to improper fraction first:

`11/18-:4 1/2=11/18-:9/2`

Now you have to change the division to multiplication by the reciprocal of the second number:

`11/18-:9/2=11/18xx2/9=11/9xx1/9=11/81`
