1 - 1/42 as a fraction

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

Summary: 1 minus 1/42 = 41/42
Since both fractions have unequal denominators, 1 minus 1/42 is an unlike fractions subtraction. For subtracting unlike fractions, you have to first find the equivalent fractions for fraction 1 and fraction 1/42 in order to have the same denominators for both fractions. Therefore, you have to find the LCM of denominators 1 and 42. 42 is the LCM of 1 and 42. Multiplying the LCM 42 with the numerators and denominators of both fractions (1 x 42/42) - (1/42 x 42/42), and simplify further in order to have the common denominator. So the equivalent fraction for 1 is 42/42 and for 1/42 is 1/42. By simplifying this fraction subtraction 42/42 - 1/42, it becomes 41/42.

Pie Chart Representation: 1 - 1/42 = 41/42

CALCULATION: 1 - 1/42 as a fraction

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

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

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

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

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

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

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

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

step 7Simplify the above expression further:
= 1/42 x 41
= 41/42
1 - 1/42 = 41/42

Hence,
1 minus 1/42 as a fraction is 41/42.

1 - 1/42 using Cross Multiplication Method:
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 1/1
Fraction B: 1/42

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

step 2 Find the product of numerator of Fraction A and denominator of Fraction B (1 x 42), find the product of numerator of Fraction B and denominator of Fraction A (1 x 1), and find the product of both denominators of Fraction A and Fraction B (1 x 42) and rewrite the equation as like the below:
= (1 x 42) - (1 x 1)/(1 x 42)

step 3 Simplify and rewrite the fraction:
= (42 - 1)/42
1 - 1/42 = 41/42

Hence,
1 minus 1/42 in fraction is 41/42
