Reducing and Raising Fractions

Reducing Fractions

You will need to be able to reduce fractions in order to get all of the points for questions related to fractions on the GED math test. This is because, for example, if you get 4/8 from your calculations, even though that is technically also a correct answer it might not appear as one of the multiple choice answers. The only correct answer available might be 1/2 so you will have to know that 1/2 is equal to 4/8. The way to reduce fractions is by finding the largest number that both the numerator and denominator can be divided by, and dividing them by that number. In the example of 4/8, both 4 and 8 can be divided by 2, which would reduce the fraction to 2/4.

However this fraction can be reduced even lower, and you should reduce fractions as much as possible.

1/2 can’t be reduced any lower since 1 is the lowest number.

Some fractions that might appear larger cannot be reduced however. For example 13/20 can’t be reduced any lower since 13 can’t be divided by anything.

Raising Fractions

Sometimes on the GED math test you will need to raise a fraction so that the fractions share a denominator (bottom part of a fraction) so that you can complete a calculation between two fractions. On the test you will know what the new denominator should be, so you only need to change the numerator (top part of a fraction).
