Fractions

Reducing

Never leave an answer as an improper fraction (the numerator is bigger than the denominator).

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.

Try the Magic Numbers:
2, 3, 5, 7, 11
Remember the number chosen must be able to go into both the numerator (top number) and denominator (bottom number) without a remainder.
Remember the Divisibility Rules:
even - use 2

ends in 5 or 0 use 5

add up to a number divisible by 3 use 3
adds up to a number divisible by 9 use 9

Go over your work - checking for any errors.

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.
