2/5 - 1/42 as a fraction

Learn how to find what is 2/5 minus 1/42 in fraction form just in a few minutes. We have covered the easiest method to write 2/5 - 1/42 as a fraction and decimal.

Summary: 2/5 minus 1/42 = 79/210
Since both fractions have unequal denominators, 2/5 minus 1/42 is an unlike fractions subtraction. For subtracting unlike fractions, you have to first find the equivalent fractions for fraction 2/5 and fraction 1/42 in order to have the same denominators for both fractions. Therefore, you have to find the LCM of denominators 5 and 42. 210 is the LCM of 5 and 42. Multiplying the LCM 210 with the numerators and denominators of both fractions (2/5 x 210/210) - (1/42 x 210/210), and simplify further in order to have the common denominator. So the equivalent fraction for 2/5 is 84/210 and for 1/42 is 5/210. By simplifying this fraction subtraction 84/210 - 5/210, it becomes 79/210.

The below workout with step by step calculation shows how to find what is the difference between two fractions by subtracting a fraction 1/42 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 1/42.
1. LCM method
2. Cross multiplication method.

(2/5) - (1/42) using LCM Method:
What is 2/5 minus 1/42 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 2/5
Fraction B: 1/42

What to be found?
(2/5) - (1/42) = ?
Find what's the difference between 2/5 and 1/42.

step 2 Compare the denominators of fractions 2/5 and 1/42 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 2/5 and 1/42 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 1/42:
The LCM of 5 and 42 is 210.

step 4 Write the fractions 2/5 and 1/42 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
= 2/5 - 1/42
= [(2 x 210)/(5 x 210)] - [(1 x 210)/(42 x 210)]

step 5 Simplify the expression to have common denominator:
= 84/210 - 5/210

step 6 Take the common values out and rewrite the above expression like the below:
= 1/210 x (84/1 - 5/1)
= 1/210 x (84 - 5)

step 7Simplify the above expression further:
= 1/210 x 79
= 79/210
2/5 - 1/42 = 79/210

Hence,
2/5 minus 1/42 as a fraction is 79/210.
