A fraction represents a division operation. Multiplying the numerator and denominator of a fraction by the same number is always an equivalent fraction.
A fraction has a numerator and a denominator. (a) You can break up a fraction from a sum in the numerator, but not in the denom- inator. You will notice that the (1/2) on the bottom line has been turned upside down to 2/1, or simply 2, and then multiplied. Fraction rules are a set of algebraic rules for working with fractions. Please help me!ĭoctor Anthony answered, starting with the rule: A simple rule to remember when dividing fractions is that you take the fraction on the bottom line (denominator), turn it upside down and multiply.

I'm in grade 6 going on to grade 7 next year. We can start with this question from Karen in 1996: Dividing Fractions
#SIMPLE MATH RULES FOR FRACTIONS HOW TO#
Here I want to look at a few of the many times we have been asked how to do it or why this works, when we did not answer with a picture. The bottom numbers (the denominators) are already the same.
Last week, we looked at how to visualize division of fractions in the process, we saw that you can multiply the first fraction (dividend) by the reciprocal of the second (divisor): “invert and multiply”. Adding Fractions To add fractions there are Three Simple Steps: Step 1: Make sure the bottom numbers (the denominators) are the same Step 2: Add the top numbers (the numerators ), put that answer over the denominator Step 3: Simplify the fraction (if possible) Example: 1 4 + 1 4 Step 1.
