2/7 - 1/42 as a fraction

Learn how to find what is 2/7 minus 1/42 in fraction form just in a few minutes. We have covered the easiest method to write 2/7 - 1/42 as a fraction and decimal.

Summary: 2/7 minus 1/42 = 11/42
Since both fractions have unequal denominators, 2/7 minus 1/42 is an unlike fractions subtraction. For subtracting unlike fractions, you have to first find the equivalent fractions for fraction 2/7 and fraction 1/42 in order to have the same denominators for both fractions. Therefore, you have to find the LCM of denominators 7 and 42. 42 is the LCM of 7 and 42. Multiplying the LCM 42 with the numerators and denominators of both fractions (2/7 x 42/42) - (1/42 x 42/42), and simplify further in order to have the common denominator. So the equivalent fraction for 2/7 is 12/42 and for 1/42 is 1/42. By simplifying this fraction subtraction 12/42 - 1/42, it becomes 11/42.

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 2/7. For different, unequal or unlike denominators, use any one of the following methods to find the equivalent fraction for 2/7 minus 1/42.
1. LCM method
2. Cross multiplication method.

(2/7) - (1/42) using LCM Method:
What is 2/7 minus 1/42 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 2/7
Fraction B: 1/42

What to be found?
(2/7) - (1/42) = ?
Find what's the difference between 2/7 and 1/42.

step 2 Compare the denominators of fractions 2/7 and 1/42 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 2/7 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 2/7 and 1/42:
The LCM of 7 and 42 is 42.

step 4 Write the fractions 2/7 and 1/42 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
= 2/7 - 1/42
= [(2 x 42)/(7 x 42)] - [(1 x 42)/(42 x 42)]

step 5 Simplify the expression to have common denominator:
= 12/42 - 1/42

step 6 Take the common values out and rewrite the above expression like the below:
= 1/42 x (12/1 - 1/1)
= 1/42 x (12 - 1)

step 7Simplify the above expression further:
= 1/42 x 11
= 11/42
2/7 - 1/42 = 11/42

Hence,
2/7 minus 1/42 as a fraction is 11/42.
