Learn how to find what is 2/5 minus 1/87 in fraction form just in a few minutes. We have covered the easiest method to write 2/5 - 1/87 as a fraction and decimal.
Summary: 2/5 minus 1/87 = 169/435
Since both fractions have unequal denominators, 2/5 minus 1/87 is an unlike fractions subtraction. For subtracting unlike fractions, you have to first find the equivalent fractions for fraction 2/5 and fraction 1/87 in order to have the same denominators for both fractions. Therefore, you have to find the LCM of denominators 5 and 87. 435 is the LCM of 5 and 87. Multiplying the LCM 435 with the numerators and denominators of both fractions (2/5 x 435/435) - (1/87 x 435/435), and simplify further in order to have the common denominator. So the equivalent fraction for 2/5 is 174/435 and for 1/87 is 5/435. By simplifying this fraction subtraction 174/435 - 5/435, it becomes 169/435.

The below workout with step by step calculation shows how to find what is the difference between two fractions by subtracting a fraction 1/87 from 2/5. For different, unequal or unlike denominators, use any one of the following methods to find the equivalent fraction for 2/5 minus 1/87.
1. LCM method
2. Cross multiplication method.
(2/5) - (1/87) using LCM Method:
What is 2/5 minus 1/87 as a fraction?
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 2/5
Fraction B: 1/87
What to be found?
(2/5) - (1/87) = ?
Find what's the difference between 2/5 and 1/87.
step 2 Compare the denominators of fractions 2/5 and 1/87 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 2/5 and 1/87 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 2/5 and 1/87:
The LCM of 5 and 87 is 435.
step 4 Write the fractions 2/5 and 1/87 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
= 2/5 - 1/87
= [(2 x 435)/(5 x 435)] - [(1 x 435)/(87 x 435)]
step 5 Simplify the expression to have common denominator:
= 174/435 - 5/435
step 6 Take the common values out and rewrite the above expression like the below:
= 1/435 x (174/1 - 5/1)
= 1/435 x (174 - 5)
step 7Simplify the above expression further:
= 1/435 x 169
= 169/435
2/5 - 1/87 = 169/435
Hence,
2/5 minus 1/87 as a fraction is 169/435.
2/5 - 1/87 using Cross Multiplication Method:
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 2/5
Fraction B: 1/87
What to be found?
(2/5)-(1/87) = ?
Find what's the difference between 2/5 and 1/87.
step 2 Find the product of numerator of Fraction A and denominator of Fraction B (2 x 87), find the product of numerator of Fraction B and denominator of Fraction A (1 x 5), and find the product of both denominators of Fraction A and Fraction B (5 x 87) and rewrite the equation as like the below:
= (2 x 87) - (1 x 5)/(5 x 87)
step 3 Simplify and rewrite the fraction:
= (174 - 5)/435
2/5 - 1/87 = 169/435
Hence,
2/5 minus 1/87 in fraction is 169/435
