1/1 - 13/20 as a fraction

Learn how to find what is 1/1 minus 13/20 in fraction form just in a few minutes. We have covered the easiest method to write 1/1 - 13/20 as a fraction and decimal.

Summary: 1/1 minus 13/20 = 7/20
Since both fractions have unequal denominators, 1/1 minus 13/20 is an unlike fractions subtraction. For subtracting unlike fractions, you have to first find the equivalent fractions for fraction 1/1 and fraction 13/20 in order to have the same denominators for both fractions. Therefore, you have to find the LCM of denominators 1 and 20. 20 is the LCM of 1 and 20. Multiplying the LCM 20 with the numerators and denominators of both fractions (1/1 x 20/20) - (13/20 x 20/20), and simplify further in order to have the common denominator. So the equivalent fraction for 1/1 is 20/20 and for 13/20 is 13/20. By simplifying this fraction subtraction 20/20 - 13/20, it becomes 7/20.

The below workout with step by step calculation shows how to find what is the difference between two fractions by subtracting a fraction 13/20 from 1/1. For different, unequal or unlike denominators, use any one of the following methods to find the equivalent fraction for 1/1 minus 13/20.
1. LCM method
2. Cross multiplication method.

(1/1) - (13/20) using LCM Method:
What is 1/1 minus 13/20 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 1/1
Fraction B: 13/20

What to be found?
(1/1) - (13/20) = ?
Find what's the difference between 1/1 and 13/20.

step 2 Compare the denominators of fractions 1/1 and 13/20 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 1/1 and 13/20 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 1/1 and 13/20:
The LCM of 1 and 20 is 20.

step 4 Write the fractions 1/1 and 13/20 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
= 1/1 - 13/20
= [(1 x 20)/(1 x 20)] - [(13 x 20)/(20 x 20)]

step 5 Simplify the expression to have common denominator:
= 20/20 - 13/20

step 6 Take the common values out and rewrite the above expression like the below:
= 1/20 x (20/1 - 13/1)
= 1/20 x (20 - 13)

step 7Simplify the above expression further:
= 1/20 x 7
= 7/20
1/1 - 13/20 = 7/20

Hence,
1/1 minus 13/20 as a fraction is 7/20.
