1 - 1/85 as a fraction

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

Summary: 1 minus 1/85 = 84/85
Since both fractions have unequal denominators, 1 minus 1/85 is an unlike fractions subtraction. For subtracting unlike fractions, you have to first find the equivalent fractions for fraction 1 and fraction 1/85 in order to have the same denominators for both fractions. Therefore, you have to find the LCM of denominators 1 and 85. 85 is the LCM of 1 and 85. Multiplying the LCM 85 with the numerators and denominators of both fractions (1 x 85/85) - (1/85 x 85/85), and simplify further in order to have the common denominator. So the equivalent fraction for 1 is 85/85 and for 1/85 is 1/85. By simplifying this fraction subtraction 85/85 - 1/85, it becomes 84/85.

Pie Chart Representation: 1 - 1/85 = 84/85

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. For different, unequal or unlike denominators, use any one of the following methods to find the equivalent fraction for 1 minus 1/85.
1. LCM method
2. Cross multiplication method.

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

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

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

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

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

step 5 Simplify the expression to have common denominator:
= 85/85 - 1/85

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

step 7Simplify the above expression further:
= 1/85 x 84
= 84/85
1 - 1/85 = 84/85

Hence,
1 minus 1/85 as a fraction is 84/85.

1 - 1/85 using Cross Multiplication Method:
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 1/1
Fraction B: 1/85

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

step 2 Find the product of numerator of Fraction A and denominator of Fraction B (1 x 85), 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 85) and rewrite the equation as like the below:
= (1 x 85) - (1 x 1)/(1 x 85)

step 3 Simplify and rewrite the fraction:
= (85 - 1)/85
1 - 1/85 = 84/85

Hence,
1 minus 1/85 in fraction is 84/85
