Fractions

Division

Fractions do not like to divide - you can hit them, threaten them, shake them, and they still won't cooperate.

THEY WILL NOT DIVIDE.

They do like to multiply.

When you see the division sign you do two things.

Change the division sign to a multiplication sign. Change the fraction that follows to its reciprocal.

Be sure to convert any mixed numbers to improper fractions before you proceed to writing reciprocals.

You can make a reciprocal of a fraction by flipping the fraction so that the top number becomes the bottom number. Therefore 3/4 has a reciprocal of 4/3.

Now multiply just as if the problem began as a multiplication problem.

Always reduce your answer to its lower terms. Remember to move the whole number then reduce the fraction (4 4/8 = 4 1/2) it sometimes helps to place the reducing number between equal lines.

2, 3, 5, 7, 11

A scrap box should be used to do the calculations. Try not to get into the habit of doing your scrap work on another piece of paper. It is much easier to find a mistake if all the work is in front of you and located close to the problem.
