1/2 - 1/85 as a fraction

Learn how to find what is 1/2 minus 1/85 in fraction form just in a few minutes. We have covered the easiest method to write 1/2 - 1/85 as a fraction and decimal.

Summary: 1/2 minus 1/85 = 83/170
Since both fractions have unequal denominators, 1/2 minus 1/85 is an unlike fractions subtraction. For subtracting unlike fractions, you have to first find the equivalent fractions for fraction 1/2 and fraction 1/85 in order to have the same denominators for both fractions. Therefore, you have to find the LCM of denominators 2 and 85. 170 is the LCM of 2 and 85. Multiplying the LCM 170 with the numerators and denominators of both fractions (1/2 x 170/170) - (1/85 x 170/170), and simplify further in order to have the common denominator. So the equivalent fraction for 1/2 is 85/170 and for 1/85 is 2/170. By simplifying this fraction subtraction 85/170 - 2/170, it becomes 83/170.

The below workout with step by step calculation shows how to find what is the difference between two fractions by subtracting a fraction 1/85 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 1/85.
1. LCM method
2. Cross multiplication method.

(1/2) - (1/85) using LCM Method:
What is 1/2 minus 1/85 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 1/2
Fraction B: 1/85

What to be found?
(1/2) - (1/85) = ?
Find what's the difference between 1/2 and 1/85.

step 2 Compare the denominators of fractions 1/2 and 1/85 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 1/2 and 1/85 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 1/85:
The LCM of 2 and 85 is 170.

step 4 Write the fractions 1/2 and 1/85 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
= 1/2 - 1/85
= [(1 x 170)/(2 x 170)] - [(1 x 170)/(85 x 170)]

step 5 Simplify the expression to have common denominator:
= 85/170 - 2/170

step 6 Take the common values out and rewrite the above expression like the below:
= 1/170 x (85/1 - 2/1)
= 1/170 x (85 - 2)

step 7Simplify the above expression further:
= 1/170 x 83
= 83/170
1/2 - 1/85 = 83/170

Hence,
1/2 minus 1/85 as a fraction is 83/170.
