13/1 - 1/10 as a fraction

Learn how to find what is 13/1 minus 1/10 in fraction form just in a few minutes. We have covered the easiest method to write 13/1 - 1/10 as a fraction and decimal.

Summary: 13/1 minus 1/10 = 129/10
Since both fractions have unequal denominators, 13/1 minus 1/10 is an unlike fractions subtraction. For subtracting unlike fractions, you have to first find the equivalent fractions for fraction 13/1 and fraction 1/10 in order to have the same denominators for both fractions. Therefore, you have to find the LCM of denominators 1 and 10. 10 is the LCM of 1 and 10. Multiplying the LCM 10 with the numerators and denominators of both fractions (13/1 x 10/10) - (1/10 x 10/10), and simplify further in order to have the common denominator. So the equivalent fraction for 13/1 is 130/10 and for 1/10 is 1/10. By simplifying this fraction subtraction 130/10 - 1/10, it becomes 129/10.

The below workout with step by step calculation shows how to find what is the difference between two fractions by subtracting a fraction 1/10 from 13/1. For different, unequal or unlike denominators, use any one of the following methods to find the equivalent fraction for 13/1 minus 1/10.
1. LCM method
2. Cross multiplication method.

(13/1) - (1/10) using LCM Method:
What is 13/1 minus 1/10 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 13/1
Fraction B: 1/10

What to be found?
(13/1) - (1/10) = ?
Find what's the difference between 13/1 and 1/10.

step 2 Compare the denominators of fractions 13/1 and 1/10 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 13/1 and 1/10 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 13/1 and 1/10:
The LCM of 1 and 10 is 10.

step 4 Write the fractions 13/1 and 1/10 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
= 13/1 - 1/10
= [(13 x 10)/(1 x 10)] - [(1 x 10)/(10 x 10)]

step 5 Simplify the expression to have common denominator:
= 130/10 - 1/10

step 6 Take the common values out and rewrite the above expression like the below:
= 1/10 x (130/1 - 1/1)
= 1/10 x (130 - 1)

step 7Simplify the above expression further:
= 1/10 x 129
= 129/10
13/1 - 1/10 = 129/10

Hence,
13/1 minus 1/10 as a fraction is 129/10.
