1/5 - 2/40 as a fraction

Learn how to find what is 1/5 minus 2/40 in fraction form just in a few minutes. We have covered the easiest method to write 1/5 - 2/40 as a fraction and decimal.

Summary: 1/5 minus 2/40 = 3/20
Since both fractions have unequal denominators, 1/5 minus 2/40 is an unlike fractions subtraction. For subtracting unlike fractions, you have to first find the equivalent fractions for fraction 1/5 and fraction 2/40 in order to have the same denominators for both fractions. Therefore, you have to find the LCM of denominators 5 and 40. 40 is the LCM of 5 and 40. Multiplying the LCM 40 with the numerators and denominators of both fractions (1/5 x 40/40) - (2/40 x 40/40), and simplify further in order to have the common denominator. So the equivalent fraction for 1/5 is 8/40 and for 2/40 is 2/40. By simplifying this fraction subtraction 8/40 - 2/40, it becomes 6/40.

The below workout with step by step calculation shows how to find what is the difference between two fractions by subtracting a fraction 2/40 from 1/5. For different, unequal or unlike denominators, use any one of the following methods to find the equivalent fraction for 1/5 minus 2/40.
1. LCM method
2. Cross multiplication method.

(1/5) - (2/40) using LCM Method:
What is 1/5 minus 2/40 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 1/5
Fraction B: 2/40

What to be found?
(1/5) - (2/40) = ?
Find what's the difference between 1/5 and 2/40.

step 2 Compare the denominators of fractions 1/5 and 2/40 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 1/5 and 2/40 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 1/5 and 2/40:
The LCM of 5 and 40 is 40.

step 4 Write the fractions 1/5 and 2/40 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
= 1/5 - 2/40
= [(1 x 40)/(5 x 40)] - [(2 x 40)/(40 x 40)]

step 5 Simplify the expression to have common denominator:
= 8/40 - 2/40

step 6 Take the common values out and rewrite the above expression like the below:
= 1/40 x (8/1 - 2/1)
= 1/40 x (8 - 2)

step 7Simplify the above expression further:
= 1/40 x 6
= 6/40
= 3/20
1/5 - 2/40 = 3/20

Hence,
1/5 minus 2/40 as a fraction is 3/20.

1/5 - 2/40 using Cross Multiplication Method:
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 1/5
Fraction B: 2/40

What to be found?
(1/5)-(2/40) = ?
Find what's the difference between 1/5 and 2/40.

step 2 Find the product of numerator of Fraction A and denominator of Fraction B (1 x 40), find the product of numerator of Fraction B and denominator of Fraction A (2 x 5), and find the product of both denominators of Fraction A and Fraction B (5 x 40) and rewrite the equation as like the below:
= (1 x 40) - (2 x 5)/(5 x 40)

step 3 Simplify and rewrite the fraction:
= (40 - 10)/200
= 30/200
= 3/20
