Learn how to find what is 2/80 minus 1/84 in fraction form just in a few minutes. We have covered the easiest method to write 2/80 - 1/84 as a fraction and decimal.

Summary: 2/80 minus 1/84 = 11/840
Since both fractions have unequal denominators, 2/80 minus 1/84 is an unlike fractions subtraction. For subtracting unlike fractions, you have to first find the equivalent fractions for fraction 2/80 and fraction 1/84 in order to have the same denominators for both fractions. Therefore, you have to find the LCM of denominators 80 and 84. 1680 is the LCM of 80 and 84. Multiplying the LCM 1680 with the numerators and denominators of both fractions (2/80 x 1680/1680) - (1/84 x 1680/1680), and simplify further in order to have the common denominator. So the equivalent fraction for 2/80 is 42/1680 and for 1/84 is 20/1680. By simplifying this fraction subtraction 42/1680 - 20/1680, it becomes 22/1680.

The below workout with step by step calculation shows how to find what is the difference between two fractions by subtracting a fraction 1/84 from 2/80. For different, unequal or unlike denominators, use any one of the following methods to find the equivalent fraction for 2/80 minus 1/84.
1. LCM method
2. Cross multiplication method.

(2/80) - (1/84) using LCM Method:
What is 2/80 minus 1/84 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 2/80
Fraction B: 1/84

What to be found?
(2/80) - (1/84) = ?
Find what's the difference between 2/80 and 1/84.

step 2 Compare the denominators of fractions 2/80 and 1/84 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 2/80 and 1/84 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 2/80 and 1/84:
The LCM of 80 and 84 is 1680.

step 4 Write the fractions 2/80 and 1/84 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
= 2/80 - 1/84
= [(2 x 1680)/(80 x 1680)] - [(1 x 1680)/(84 x 1680)]

step 5 Simplify the expression to have common denominator:
= 42/1680 - 20/1680

step 6 Take the common values out and rewrite the above expression like the below:
= 1/1680 x (42/1 - 20/1)
= 1/1680 x (42 - 20)

step 7Simplify the above expression further:
= 1/1680 x 22
= 22/1680
= 11/840
2/80 - 1/84 = 11/840

Hence,
2/80 minus 1/84 as a fraction is 11/840.
