8/1 - 3/5 as a fraction

Learn how to find what is 8/1 minus 3/5 in fraction form just in a few minutes. We have covered the easiest method to write 8/1 - 3/5 as a fraction and decimal.

Summary: 8/1 minus 3/5 = 37/5
Since both fractions have unequal denominators, 8/1 minus 3/5 is an unlike fractions subtraction. For subtracting unlike fractions, you have to first find the equivalent fractions for fraction 8/1 and fraction 3/5 in order to have the same denominators for both fractions. Therefore, you have to find the LCM of denominators 1 and 5. 5 is the LCM of 1 and 5. Multiplying the LCM 5 with the numerators and denominators of both fractions (8/1 x 5/5) - (3/5 x 5/5), and simplify further in order to have the common denominator. So the equivalent fraction for 8/1 is 40/5 and for 3/5 is 3/5. By simplifying this fraction subtraction 40/5 - 3/5, it becomes 37/5.

The below workout with step by step calculation shows how to find what is the difference between two fractions by subtracting a fraction 3/5 from 8/1. For different, unequal or unlike denominators, use any one of the following methods to find the equivalent fraction for 8/1 minus 3/5.
1. LCM method
2. Cross multiplication method.

(8/1) - (3/5) using LCM Method:
What is 8/1 minus 3/5 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 8/1
Fraction B: 3/5

What to be found?
(8/1) - (3/5) = ?
Find what's the difference between 8/1 and 3/5.

step 2 Compare the denominators of fractions 8/1 and 3/5 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 8/1 and 3/5 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 8/1 and 3/5:
The LCM of 1 and 5 is 5.

step 4 Write the fractions 8/1 and 3/5 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
= 8/1 - 3/5
= [(8 x 5)/(1 x 5)] - [(3 x 5)/(5 x 5)]

step 5 Simplify the expression to have common denominator:
= 40/5 - 3/5

step 6 Take the common values out and rewrite the above expression like the below:
= 1/5 x (40/1 - 3/1)
= 1/5 x (40 - 3)

step 7Simplify the above expression further:
= 1/5 x 37
= 37/5
8/1 - 3/5 = 37/5

Hence,
8/1 minus 3/5 as a fraction is 37/5.
