15/1 - 5/3 as a fraction

Learn how to find what is 15/1 minus 5/3 in fraction form just in a few minutes. We have covered the easiest method to write 15/1 - 5/3 as a fraction and decimal.

Summary: 15/1 minus 5/3 = 40/3
Since both fractions have unequal denominators, 15/1 minus 5/3 is an unlike fractions subtraction. For subtracting unlike fractions, you have to first find the equivalent fractions for fraction 15/1 and fraction 5/3 in order to have the same denominators for both fractions. Therefore, you have to find the LCM of denominators 1 and 3. 3 is the LCM of 1 and 3. Multiplying the LCM 3 with the numerators and denominators of both fractions (15/1 x 3/3) - (5/3 x 3/3), and simplify further in order to have the common denominator. So the equivalent fraction for 15/1 is 45/3 and for 5/3 is 5/3. By simplifying this fraction subtraction 45/3 - 5/3, it becomes 40/3.

The below workout with step by step calculation shows how to find what is the difference between two fractions by subtracting a fraction 5/3 from 15/1. For different, unequal or unlike denominators, use any one of the following methods to find the equivalent fraction for 15/1 minus 5/3.
1. LCM method
2. Cross multiplication method.

(15/1) - (5/3) using LCM Method:
What is 15/1 minus 5/3 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 15/1
Fraction B: 5/3

What to be found?
(15/1) - (5/3) = ?
Find what's the difference between 15/1 and 5/3.

step 2 Compare the denominators of fractions 15/1 and 5/3 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 15/1 and 5/3 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 15/1 and 5/3:
The LCM of 1 and 3 is 3.

step 4 Write the fractions 15/1 and 5/3 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
= 15/1 - 5/3
= [(15 x 3)/(1 x 3)] - [(5 x 3)/(3 x 3)]

step 5 Simplify the expression to have common denominator:
= 45/3 - 5/3

step 6 Take the common values out and rewrite the above expression like the below:
= 1/3 x (45/1 - 5/1)
= 1/3 x (45 - 5)

step 7Simplify the above expression further:
= 1/3 x 40
= 40/3
15/1 - 5/3 = 40/3

Hence,
15/1 minus 5/3 as a fraction is 40/3.
