1 - 2/42 as a fraction

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

Summary: 1 minus 2/42 = 20/21
Since both fractions have unequal denominators, 1 minus 2/42 is an unlike fractions subtraction. For subtracting unlike fractions, you have to first find the equivalent fractions for fraction 1 and fraction 2/42 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) - (2/42 x 42/42), and simplify further in order to have the common denominator. So the equivalent fraction for 1 is 42/42 and for 2/42 is 2/42. By simplifying this fraction subtraction 42/42 - 2/42, it becomes 40/42.

Pie Chart Representation: 1 - 2/42 = 20/21

CALCULATION: 1 - 2/42 as a fraction
1 - 2/42 = (?)
1/1 - 2/42 = [(1 x 42) - (2 x 1)]/(1 x 42)
= (42 - 2)/42
= 40/42
= (2 x 20)/(2 x 21)
= 20/21
1 - 2/42 = 20/21
1 minus 2/42 as a fraction is 20/21.

where
1 is a whole number as a minuend,
2/42 is a proper fraction as a subtrahend,
20/21 is the difference between 1 and 2/42.

The below workout with step by step calculation shows how to find what is the difference between two fractions by subtracting a fraction 2/42 from 1. For different, unequal or unlike denominators, use any one of the following methods to find the equivalent fraction for 1 minus 2/42.
1. LCM method
2. Cross multiplication method.

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

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

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

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

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

step 5 Simplify the expression to have common denominator:
= 42/42 - 2/42

step 6 Take the common values out and rewrite the above expression like the below:
= 1/42 x (42/1 - 2/1)
= 1/42 x (42 - 2)

step 7Simplify the above expression further:
= 1/42 x 40
= 40/42
= 20/21
1 - 2/42 = 20/21

Hence,
1 minus 2/42 as a fraction is 20/21.

1 - 2/42 using Cross Multiplication Method:
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 1/1
Fraction B: 2/42

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

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 (2 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) - (2 x 1)/(1 x 42)

step 3 Simplify and rewrite the fraction:
= (42 - 2)/42
= 40/42
= 20/21
1 - 2/42 = 20/21

Hence,
1 minus 2/42 in fraction is 20/21
