find the LCD
5/6-8/12
LCD=12
divide in the denominator 2 1
multiply in the numerator 10 12
10/12 1/12 subtract the numerator = 9 copy the denominator 12
9/12
find the LCD
5/6-8/12
LCD=12
divide in the denominator 2 1
multiply in the numerator 10 12
10/12 1/12 subtract the numerator = 9 copy the denominator 12
9/12
Subtraction of dissimilar fractions can be both and easy and hard. Here is the example:
Mrs. Santos bought 9 and 1/8 meters of curtain cloth. She used 3 and 5/6 meters to make curtain for the master's bedroom window. How many meters of cloth were not used? To find out, we subtract 3 and 5/6 from 9 and 1/8.
find the LCD Rename dissimilar mixed compare the
9 1/8 numbers to equivalent fraction in the
-3 5/6 mixed numbers using LCD minuend and the
LCD=24 9 1/8= 9 1 x 3= 9 3 subtrahend. Rename
8 x 3 24 and regroup the
-3 5/6= 3 5 x 4=3 20 minuend.
6 x 4 24 9 1/8= 9 3/24= 9 + 3/24
=8 + 1 + 3/24
=8 + 24/24 + 3/24
=8 27/24
And lastly. Subtract... Write the digit in the lowest term.
9 1/8= 8 27/24
- 3 5/6= 3 20/24
5 7/24
And the answer is................................. 5 7/24
