Fraction Review

-A fractions compares a part to a total

-A fraction look like 3/4

-A fraction has a numerator and a denominator

• a number that divides into another number exactly, without leaving a remainder

• A factor is a number when multiplied with another number produces a given number

• the meaning of a multiple is the product result of one number multiplied by another number

• aka THE RESULT

• aka THE ANSWER

• aka THE PRODUCT

Equivalent means...

Equal to

Has the same value

Look at the fractions and the pictures that represent them.

• You can multiply the numerator and denominator by the same number

• You can divide the numerator and denominator by the same number

• Equivalent Fractions have the same value, even though they may look different.

• 1/2 = 2/4 = 4/8

• The rule to remember is:

  "Change the bottom using multiply or divide, And the same to the top must be applied"

6​

What could some equivalent fractions of 4/6 be? *Hint: you can go up by multiplying or down by dividing!

Let's find out how to do the "bottoms up" method!​

Look at the image to the left.

​Equivalent fractions have different numerators and denominators, but their value is the same

​

• Reduce

• Simplest Terms/Form

• Lowest Terms/Form

Also known as reducing!!

rewriting a fraction using the smallest numerator and denominator without changing the value of the fraction.

Whatever you do to the top, you have to do the same to the bottom.

We use simplification to find a fraction that is easier to use. We try to find familiar fractions that we have worked with before. For example, if we have the fraction, 36/40, we could simplify to 9/10.

• Look at the numerator and denominator

• Look for any patterns or fact families

• LIST OUT THE FACTORS OF BOTH THE NUMERATOR AND DENOMINATOR

This happens often! Don't panic. Do what you know and reduce, reduce, reduce! Until you can't anymore! 

Select the GCF you've listed. For example, let's say our fraction is 8/24 and you choose 4 (instead of 8) as your GCF. Divide both the numerator and denominator by 4. You will get 2/6. Start the process over. List factors of 2 and 6. Divide by the GCF. You will get 1/3.
