Things You'll Need:
- Paper
- pencil(all math should be done in pencil, even on a college level.)

Step 1
To make this concept simplistic, first let's review parts of a fraction. In 3/4, the 3 is in the numerator of the fraction and the 4 is in the denominator. Use the (d) in denominator as a clue that the number located in the bottom of the fraction will always be in the
(d)enominator.
Now given the problem----------3/4 divided by 2/5, the first step is to find the reciprocal of the second fraction (You find it by flipping the fraction. 2/5 becomes 5/2. Next, rewrite the new fraction------instead of 3/4 divided by 2/5 the new problem becomes 3/4 divided by 5/2. -
Step 2
*** We must now change the new problem to a multiplication problem.
Our new problem becomes----3/4 X 5/2
Multiply the two numerators together----3 and 5 which equals 15
Multiply the two denominators together--4 and 2 which equals 8
Form an answer-- the new numerator is 15 and the new denominator is 8
Thus we have an answer or (product) of 15/8 -
Step 3
Yes, our answer(product) can be 15/8, This type of fraction is called an improper fraction.
Look at this new problem for a quick review
3/8 divided by 4/8, becomes
3/8 divided by 8/4, next create a multiplication problem
3/8 X 8/4
next, multiply the numerators 3 and 8=24
then, multiply the denominators 8 and 4=32
Thus, the answer becomes 24/32
