1 - 2/87 as a fraction

Learn how to find what is 1 minus 2/87 in fraction form just in a few minutes. We have covered the easiest method to write 1 - 2/87 as a fraction and decimal.

Summary: 1 minus 2/87 = 85/87
Since both fractions have unequal denominators, 1 minus 2/87 is an unlike fractions subtraction. For subtracting unlike fractions, you have to first find the equivalent fractions for fraction 1 and fraction 2/87 in order to have the same denominators for both fractions. Therefore, you have to find the LCM of denominators 1 and 87. 87 is the LCM of 1 and 87. Multiplying the LCM 87 with the numerators and denominators of both fractions (1 x 87/87) - (2/87 x 87/87), and simplify further in order to have the common denominator. So the equivalent fraction for 1 is 87/87 and for 2/87 is 2/87. By simplifying this fraction subtraction 87/87 - 2/87, it becomes 85/87.

Pie Chart Representation: 1 - 2/87 = 85/87

The below workout with step by step calculation shows how to find what is the difference between two fractions by subtracting a fraction 2/87 from 1. For different, unequal or unlike denominators, use any one of the following methods to find the equivalent fraction for 1 minus 2/87.
1. LCM method
2. Cross multiplication method.

(1) - (2/87) using LCM Method:
What is 1 minus 2/87 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 1/1
Fraction B: 2/87

What to be found?
(1) - (2/87) = ?
Find what's the difference between 1 and 2/87.

step 2 Compare the denominators of fractions 1 and 2/87 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 1 and 2/87 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 2/87:
The LCM of 1 and 87 is 87.

step 4 Write the fractions 1 and 2/87 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
= 1 - 2/87
= [(1 x 87)/(1 x 87)] - [(2 x 87)/(87 x 87)]

step 5 Simplify the expression to have common denominator:
= 87/87 - 2/87

step 6 Take the common values out and rewrite the above expression like the below:
= 1/87 x (87/1 - 2/1)
= 1/87 x (87 - 2)

step 7Simplify the above expression further:
= 1/87 x 85
= 85/87
1 - 2/87 = 85/87

Hence,
1 minus 2/87 as a fraction is 85/87.

1 - 2/87 using Cross Multiplication Method:
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 1/1
Fraction B: 2/87

What to be found?
(1)-(2/87) = ?
Find what's the difference between 1 and 2/87.

step 2 Find the product of numerator of Fraction A and denominator of Fraction B (1 x 87), find the product of numerator of Fraction B and denominator of Fraction A (2 x 1), and find the product of both denominators of Fraction A and Fraction B (1 x 87) and rewrite the equation as like the below:
= (1 x 87) - (2 x 1)/(1 x 87)

step 3 Simplify and rewrite the fraction:
= (87 - 2)/87
1 - 2/87 = 85/87

Hence,
1 minus 2/87 in fraction is 85/87
