1/3 - 2/20 as a fraction

Learn how to find what is 1/3 minus 2/20 in fraction form just in a few minutes. We have covered the easiest method to write 1/3 - 2/20 as a fraction and decimal.

Summary: 1/3 minus 2/20 = 7/30
Since both fractions have unequal denominators, 1/3 minus 2/20 is an unlike fractions subtraction. For subtracting unlike fractions, you have to first find the equivalent fractions for fraction 1/3 and fraction 2/20 in order to have the same denominators for both fractions. Therefore, you have to find the LCM of denominators 3 and 20. 60 is the LCM of 3 and 20. Multiplying the LCM 60 with the numerators and denominators of both fractions (1/3 x 60/60) - (2/20 x 60/60), and simplify further in order to have the common denominator. So the equivalent fraction for 1/3 is 20/60 and for 2/20 is 6/60. By simplifying this fraction subtraction 20/60 - 6/60, it becomes 14/60.

The below workout with step by step calculation shows how to find what is the difference between two fractions by subtracting a fraction 2/20 from 1/3. For different, unequal or unlike denominators, use any one of the following methods to find the equivalent fraction for 1/3 minus 2/20.
1. LCM method
2. Cross multiplication method.

(1/3) - (2/20) using LCM Method:
What is 1/3 minus 2/20 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 1/3
Fraction B: 2/20

What to be found?
(1/3) - (2/20) = ?
Find what's the difference between 1/3 and 2/20.

step 2 Compare the denominators of fractions 1/3 and 2/20 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 1/3 and 2/20 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 1/3 and 2/20:
The LCM of 3 and 20 is 60.

step 4 Write the fractions 1/3 and 2/20 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
= 1/3 - 2/20
= [(1 x 60)/(3 x 60)] - [(2 x 60)/(20 x 60)]

step 5 Simplify the expression to have common denominator:
= 20/60 - 6/60

step 6 Take the common values out and rewrite the above expression like the below:
= 1/60 x (20/1 - 6/1)
= 1/60 x (20 - 6)

step 7Simplify the above expression further:
= 1/60 x 14
= 14/60
= 7/30
1/3 - 2/20 = 7/30

Hence,
1/3 minus 2/20 as a fraction is 7/30.

1/3 - 2/20 using Cross Multiplication Method:
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 1/3
Fraction B: 2/20

What to be found?
(1/3)-(2/20) = ?
Find what's the difference between 1/3 and 2/20.

step 2 Find the product of numerator of Fraction A and denominator of Fraction B (1 x 20), find the product of numerator of Fraction B and denominator of Fraction A (2 x 3), and find the product of both denominators of Fraction A and Fraction B (3 x 20) and rewrite the equation as like the below:
= (1 x 20) - (2 x 3)/(3 x 20)

step 3 Simplify and rewrite the fraction:
= (20 - 6)/60
= 14/60
= 7/30
