The following steps will be useful to subtract fractions with like denominators.
Step 1 :
When two fractions with the same denominator are subtracted, take the denominator once.
Step 2 :
Now, subtract the numerators and simplify, if required.
Example 1 :
Find the value of :
1/5 - 2/5
Solution :
1/5 - 2/5
The given two fractions have the same denominator. That is 5.
So, take the denominator once and subtract the numerators.
= (1 - 2) / 5
= -1 / 5
Therefore,
1/5 - 2/5 = -1/5
Example 2 :
Subtract 2/14 from 5 / 14.
Solution :
5/14 - 2/14
The given two fractions have the same denominator. That is 14.
So, take the denominator once and subtract the numerators.
= (5 - 2) / 14
= 3 / 14
Therefore,
5/14 - 2/14 = 3/14
Example 3 :
Subtract 47/125 from 87/125.
Solution :
87/125 - 47/125
The given two fractions have the same denominator. That is 125.
So, take the denominator once and subtract the numerators.
= (87 - 47) / 125
= 40 / 125
Simplify.
= 8 / 25
Therefore,
87/125 - 47/125 = 8/25
Example 4 :
Find the value of :
1/5 + 2/5 - 2/5
Solution :
1/5 + 2/5 - 2/5
The given fractions have the same denominator. That is 5.
So, take the denominator once and simplify the numerators.
= (1 + 2 - 2) / 5
= 1 / 5
Therefore,
1/5 + 2/5 + 2/5 = 1/5
Example 5 :
Find the value of :
2/13 - 7/13 + 12/13 - 5/13
Solution :
2/13 - 7/13 + 12/13 - 5/13
The given fractions have the same denominator. That is 13.
So, take the denominator once and simplify the numerators.
= (2 - 7 + 12 - 5) / 13
= 2 / 13
Therefore,
2/13 - 7/13 + 12/13 - 5/13 = 2/13
