Math 6A ( Periods 2 & 5)

Fractions and Decimals on the Number line 6.3

How can we use a number line to compare positive and negative fractions and decimals?

Can you name a number between 1 3/6 and 1 4/6? Did you use equivalent fractions?

You can graph negative fractions and decimals in a similar manner to what we did with integers!  

Compare -1/2 and -3/4 
Notice -3/4 is farther to the left from 0. -1/2 is to the right of -3/4

So -1/2 > -3/4

Compare -4 5/6 and – 4 1/6

When you graph these two numbers, you notice that -4 5/6 is to the left of -4 1/6

So -4 5/6 < -4 1/6

Similarly with decimals

Comparing -3.08 and -3.8

-3.08 is to the right of -3.8 so

-3.08 > -3.8
