Dividing fractions
To divide two fractions, find the reciprocal of the second fraction (invert it) and multiply.
$${8/9}÷{2/7}={8/9}×{7/2}=56/18$$
You can simplify/reduce the resulting fraction (or convert to a mixed number):
$${56÷2}/{18÷2}=28/9={3×9+1}/9=3{1/9}$$
Dividing fractions by a whole number
Rewrite the whole number as a fraction (just put the whole number over 1 as denominator):
$${4/5}÷7={4/5}÷{7/1}=4/5×1/7=4/35$$
