Greatest Common Factor
The 5-step planTo simplify fractions, you need to look for the greatest common factor, also called the GCF. This is the highest positive cardinal number both the numerator and denominator can be divided by, without leaving remainders. This skill is important and you need to master it before you can continue with other fractions exercises, such as multiplication and division with fractions. In the 5-step plan we look for the GCF. At step 1 you get 10 open questions. At step 2 you can drag the answers. At step 3 there are more open questions, but more difficult than at step 1. At step 4 you get multiple choice questions, and at step 5 you need to get the diploma.
Step 1 - What is the GCF?
Step 2 - Drag the GCF to the fraction
Step 3 - What is the GCF?
Step 4 - Multiple choice, choose the GCF
