Subtracting Fractions With Like Denominators

This is what we learned in class:

5/6-1/6=4/6=2/3

Show with a picture or a model:

3/4-1/4=2/4=1/2

1/3-1/3=0/3=0

Solve the following:

7/10-3/10=4/10=2/5

1-1/9=9-1/9=8/9

Adding Fractions.

Draw pictures to show the following:

1 + 1 = 2
4 4 4




2 + 1 = 3
3 3 3

simple term

one over one, 100% , 1
1

Use a diagram to show

1+ 5 = 6
8 8 8



5+ 1 = 6
12 12 12




4+ 2 = 6
9 9 9
short term

2
3




Rule: When adding with like denominators (same bottom number) add the numerators,denominators stays the same.
