1/2 - 2/71 as a fraction

Learn how to find what is 1/2 minus 2/71 in fraction form just in a few minutes. We have covered the easiest method to write 1/2 - 2/71 as a fraction and decimal.

Summary: 1/2 minus 2/71 = 67/142
Since both fractions have unequal denominators, 1/2 minus 2/71 is an unlike fractions subtraction. For subtracting unlike fractions, you have to first find the equivalent fractions for fraction 1/2 and fraction 2/71 in order to have the same denominators for both fractions. Therefore, you have to find the LCM of denominators 2 and 71. 142 is the LCM of 2 and 71. Multiplying the LCM 142 with the numerators and denominators of both fractions (1/2 x 142/142) - (2/71 x 142/142), and simplify further in order to have the common denominator. So the equivalent fraction for 1/2 is 71/142 and for 2/71 is 4/142. By simplifying this fraction subtraction 71/142 - 4/142, it becomes 67/142.

The below workout with step by step calculation shows how to find what is the difference between two fractions by subtracting a fraction 2/71 from 1/2. For different, unequal or unlike denominators, use any one of the following methods to find the equivalent fraction for 1/2 minus 2/71.
1. LCM method
2. Cross multiplication method.

(1/2) - (2/71) using LCM Method:
What is 1/2 minus 2/71 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 1/2
Fraction B: 2/71

What to be found?
(1/2) - (2/71) = ?
Find what's the difference between 1/2 and 2/71.

step 2 Compare the denominators of fractions 1/2 and 2/71 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 1/2 and 2/71 are not equal, it is said to be unlike fractions subtraction.

step 3For unlike fractions subtraction, find the LCM (least common multiple) of both denominators of fractions 1/2 and 2/71:
The LCM of 2 and 71 is 142.

step 4 Write the fractions 1/2 and 2/71 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
= 1/2 - 2/71
= [(1 x 142)/(2 x 142)] - [(2 x 142)/(71 x 142)]

step 5 Simplify the expression to have common denominator:
= 71/142 - 4/142

step 6 Take the common values out and rewrite the above expression like the below:
= 1/142 x (71/1 - 4/1)
= 1/142 x (71 - 4)

step 7Simplify the above expression further:
= 1/142 x 67
= 67/142
1/2 - 2/71 = 67/142

Hence,
1/2 minus 2/71 as a fraction is 67/142.
