1/1 - 1/82 as a fraction

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

Summary: 1/1 minus 1/82 = 81/82
Since both fractions have unequal denominators, 1/1 minus 1/82 is an unlike fractions subtraction. For subtracting unlike fractions, you have to first find the equivalent fractions for fraction 1/1 and fraction 1/82 in order to have the same denominators for both fractions. Therefore, you have to find the LCM of denominators 1 and 82. 82 is the LCM of 1 and 82. Multiplying the LCM 82 with the numerators and denominators of both fractions (1/1 x 82/82) - (1/82 x 82/82), and simplify further in order to have the common denominator. So the equivalent fraction for 1/1 is 82/82 and for 1/82 is 1/82. By simplifying this fraction subtraction 82/82 - 1/82, it becomes 81/82.

Pie Chart Representation: 1/1 - 1/82 = 81/82

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 1/1. For different, unequal or unlike denominators, use any one of the following methods to find the equivalent fraction for 1/1 minus 1/82.
1. LCM method
2. Cross multiplication method.

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

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

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

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

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

step 5 Simplify the expression to have common denominator:
= 82/82 - 1/82

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

step 7Simplify the above expression further:
= 1/82 x 81
= 81/82
1/1 - 1/82 = 81/82

Hence,
1/1 minus 1/82 as a fraction is 81/82.

1/1 - 1/82 using Cross Multiplication Method:
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 1/1
Fraction B: 1/82

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

step 2 Find the product of numerator of Fraction A and denominator of Fraction B (1 x 82), find the product of numerator of Fraction B and denominator of Fraction A (1 x 1), and find the product of both denominators of Fraction A and Fraction B (1 x 82) and rewrite the equation as like the below:
= (1 x 82) - (1 x 1)/(1 x 82)

step 3 Simplify and rewrite the fraction:
= (82 - 1)/82
1/1 - 1/82 = 81/82

Hence,
1/1 minus 1/82 in fraction is 81/82
