We've now looked a lot at placing fractions on number lines. Do you remember how to show whole numbers as fractions on the number line? At 2 on the number line, you multiply the denominator times 2 to get the top number of the fraction. So if the denominator is 4, then two wholes written as a fraction is 
. If the denominator is 2, then three wholes written as a fraction is 
.
We also looked at placing fractions on the number line. It's important to remember that the denominator tells us what number line we're dealing with. If the fraction is 
, then the denominator for each number on the number line will be 5. You also know that the first number on the number line tells us how many parts are in a whole. If our denominator is 5, what is the first number on the number line? The first number is 
. We know that each whole has five parts. If you count up the first four parts on the number line, you know to place 
right before 
. Where would you place 
? Count eight parts up the number line. You're in the right area if you landed between 
and 
.
