1/2 - 1/87 as a fraction

Learn how to find what is 1/2 minus 1/87 in fraction form just in a few minutes. We have covered the easiest method to write 1/2 - 1/87 as a fraction and decimal.

Summary: 1/2 minus 1/87 = 85/174
Since both fractions have unequal denominators, 1/2 minus 1/87 is an unlike fractions subtraction. For subtracting unlike fractions, you have to first find the equivalent fractions for fraction 1/2 and fraction 1/87 in order to have the same denominators for both fractions. Therefore, you have to find the LCM of denominators 2 and 87. 174 is the LCM of 2 and 87. Multiplying the LCM 174 with the numerators and denominators of both fractions (1/2 x 174/174) - (1/87 x 174/174), and simplify further in order to have the common denominator. So the equivalent fraction for 1/2 is 87/174 and for 1/87 is 2/174. By simplifying this fraction subtraction 87/174 - 2/174, it becomes 85/174.

The below workout with step by step calculation shows how to find what is the difference between two fractions by subtracting a fraction 1/87 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 1/87.
1. LCM method
2. Cross multiplication method.

(1/2) - (1/87) using LCM Method:
What is 1/2 minus 1/87 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 1/2
Fraction B: 1/87

What to be found?
(1/2) - (1/87) = ?
Find what's the difference between 1/2 and 1/87.

step 2 Compare the denominators of fractions 1/2 and 1/87 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 1/2 and 1/87 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 1/87:
The LCM of 2 and 87 is 174.

step 4 Write the fractions 1/2 and 1/87 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
= 1/2 - 1/87
= [(1 x 174)/(2 x 174)] - [(1 x 174)/(87 x 174)]

step 5 Simplify the expression to have common denominator:
= 87/174 - 2/174

step 6 Take the common values out and rewrite the above expression like the below:
= 1/174 x (87/1 - 2/1)
= 1/174 x (87 - 2)

step 7Simplify the above expression further:
= 1/174 x 85
= 85/174
1/2 - 1/87 = 85/174

Hence,
1/2 minus 1/87 as a fraction is 85/174.
