5/1 - 7/10 as a fraction

Learn how to find what is 5/1 minus 7/10 in fraction form just in a few minutes. We have covered the easiest method to write 5/1 - 7/10 as a fraction and decimal.

Summary: 5/1 minus 7/10 = 43/10
Since both fractions have unequal denominators, 5/1 minus 7/10 is an unlike fractions subtraction. For subtracting unlike fractions, you have to first find the equivalent fractions for fraction 5/1 and fraction 7/10 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 (5/1 x 10/10) - (7/10 x 10/10), and simplify further in order to have the common denominator. So the equivalent fraction for 5/1 is 50/10 and for 7/10 is 7/10. By simplifying this fraction subtraction 50/10 - 7/10, it becomes 43/10.

The below workout with step by step calculation shows how to find what is the difference between two fractions by subtracting a fraction 7/10 from 5/1. For different, unequal or unlike denominators, use any one of the following methods to find the equivalent fraction for 5/1 minus 7/10.
1. LCM method
2. Cross multiplication method.

(5/1) - (7/10) using LCM Method:
What is 5/1 minus 7/10 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 5/1
Fraction B: 7/10

What to be found?
(5/1) - (7/10) = ?
Find what's the difference between 5/1 and 7/10.

step 2 Compare the denominators of fractions 5/1 and 7/10 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 5/1 and 7/10 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 5/1 and 7/10:
The LCM of 1 and 10 is 10.

step 4 Write the fractions 5/1 and 7/10 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
= 5/1 - 7/10
= [(5 x 10)/(1 x 10)] - [(7 x 10)/(10 x 10)]

step 5 Simplify the expression to have common denominator:
= 50/10 - 7/10

step 6 Take the common values out and rewrite the above expression like the below:
= 1/10 x (50/1 - 7/1)
= 1/10 x (50 - 7)

step 7Simplify the above expression further:
= 1/10 x 43
= 43/10
5/1 - 7/10 = 43/10

Hence,
5/1 minus 7/10 as a fraction is 43/10.
