2/4 - 1/82 as a fraction

Learn how to find what is 2/4 minus 1/82 in fraction form just in a few minutes. We have covered the easiest method to write 2/4 - 1/82 as a fraction and decimal.

Summary: 2/4 minus 1/82 = 20/41
Since both fractions have unequal denominators, 2/4 minus 1/82 is an unlike fractions subtraction. For subtracting unlike fractions, you have to first find the equivalent fractions for fraction 2/4 and fraction 1/82 in order to have the same denominators for both fractions. Therefore, you have to find the LCM of denominators 4 and 82. 164 is the LCM of 4 and 82. Multiplying the LCM 164 with the numerators and denominators of both fractions (2/4 x 164/164) - (1/82 x 164/164), and simplify further in order to have the common denominator. So the equivalent fraction for 2/4 is 82/164 and for 1/82 is 2/164. By simplifying this fraction subtraction 82/164 - 2/164, it becomes 80/164.

The below workout with step by step calculation shows how to find what is the difference between two fractions by subtracting a fraction 1/82 from 2/4. For different, unequal or unlike denominators, use any one of the following methods to find the equivalent fraction for 2/4 minus 1/82.
1. LCM method
2. Cross multiplication method.

(2/4) - (1/82) using LCM Method:
What is 2/4 minus 1/82 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 2/4
Fraction B: 1/82

What to be found?
(2/4) - (1/82) = ?
Find what's the difference between 2/4 and 1/82.

step 2 Compare the denominators of fractions 2/4 and 1/82 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 2/4 and 1/82 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 2/4 and 1/82:
The LCM of 4 and 82 is 164.

step 4 Write the fractions 2/4 and 1/82 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
= 2/4 - 1/82
= [(2 x 164)/(4 x 164)] - [(1 x 164)/(82 x 164)]

step 5 Simplify the expression to have common denominator:
= 82/164 - 2/164

step 6 Take the common values out and rewrite the above expression like the below:
= 1/164 x (82/1 - 2/1)
= 1/164 x (82 - 2)

step 7Simplify the above expression further:
= 1/164 x 80
= 80/164
= 20/41
2/4 - 1/82 = 20/41

Hence,
2/4 minus 1/82 as a fraction is 20/41.
