2 3/4 - 1 1/4
One method use fraction strips
* Second method = Subtract whole numbers
Answer the following :
a) 2 2/3 - 1 1/3 =
2 - 1 = 1
2/3 - 1/3 = 1/3
1 1/3
b) 3 7/8 - 1 3/8 =
3 - 1 = 2
7/8 - 3/8 = 4/8
2 4/8
Lowest terms = 2 2/4, 2 1/2
c) 4 3/4 - 1/4 =
3/4 - 1/4= 2/4
4 2/4
Lowest terms - 4 1/2
Unlike Denominators
- Find the common denominator
We don't want to have a whole number (2) and a negative fraction so we must regroup
* ANOTHER WAY TO REGROUP
Steps :
1. Subtract the whole numbers
2. Subtract fractions
3. Combine them
Answer the following ; a ) 4 1/4 - 3 2/5
b) 4 1/4 - 7/8
