 What is an Equivalent Fraction  Why use Equivalent Fractions?  How to find Equivalent fractions?  Equivalent means“Equal”  The numerator (top number) is different  The denominator (bottom number) is different  Although they are different numbers they are the same amount. But how you may ask??

So this tells us that 2/3 is the same as 8/12 Image source: visualfractions.com

One Whole

2 The denominator (how many pieces its cut into) Cut them in half 1 The numerator

½ and also 2/4 Cut them in half again I still show the same thing, but now I also show a new fraction that is equal (equivalent)

They are the Same!! ½ 2/4 One half is equivalent to two quarters!!

Why use Equivalent Fractions? Equivalent Fractions make large numbers easier to deal with Smaller numbers are simple = =2

To Find Equivalent Fractions Multiple the numerator and the denominator by the same number 1 X = 20

Find Equivalent Fractions Both numbers have 3 as the common factor 15 Divide by = Divide by 3 15 Start thinking ahead can we make 3/15 smaller?? What number to 5 and 15 have in common?

Now you try it The top picture is cut into fourths The bottom picture is cut into eights. How many eights would be equal to the ¾ that are shaded in blue.

Did you get the answer right? 6, that’s right 6/8 equals ¾ 6 divided by 2= 3 8 divided by 2= 4
