Dividing two fractions is the same as multiplying the first fraction by the reciprocal value of the second fraction. The first sub-step is to find the reciprocal (reverse the numerator and denominator, reciprocal of 1
3
is 3
1
) of the second fraction. Next, multiply the two numerators. Then, multiply the two denominators.
In words - three divided by one third = nine.
Subtract: 9 - the result of step No. 1 = 9 - 9 = 0
Add: the result of step No. 2 + 1 = 0 + 1 = 1
