Remember? You know how to convert fractions into other equivalent fractions.
We can also reverse the process. Then it is called SIMPLIFYING:

When you simplify, the numerator and the denominator are divided by the same number.
To simplify, you need to find a number by which you can divide the numerator and denominator. That number has to “go” both into the numerator and denominator. Or, we can say that the numerator and the denominator have to be divisible by that same number. |

The ideas in this fraction lesson are taken from the Math Mammoth Fractions 2 book. Only a few examples of each problem type are shown; you should make more problems of each kind for the student.
| Math Mammoth Fractions 2 A self-teaching worktext that teaches fractions using visual models, a sequel to Math Mammoth Fractions 1. The book covers simplifying fractions, multiplication and division of fractions and mixed numbers, converting fractions to decimals, and ratios. Available as an affordable download ($5.00), and also as a printed copy. |
