7/1 - 2/15 as a fraction

Learn how to find what is 7/1 minus 2/15 in fraction form just in a few minutes. We have covered the easiest method to write 7/1 - 2/15 as a fraction and decimal.

Summary: 7/1 minus 2/15 = 103/15
Since both fractions have unequal denominators, 7/1 minus 2/15 is an unlike fractions subtraction. For subtracting unlike fractions, you have to first find the equivalent fractions for fraction 7/1 and fraction 2/15 in order to have the same denominators for both fractions. Therefore, you have to find the LCM of denominators 1 and 15. 15 is the LCM of 1 and 15. Multiplying the LCM 15 with the numerators and denominators of both fractions (7/1 x 15/15) - (2/15 x 15/15), and simplify further in order to have the common denominator. So the equivalent fraction for 7/1 is 105/15 and for 2/15 is 2/15. By simplifying this fraction subtraction 105/15 - 2/15, it becomes 103/15.

The below workout with step by step calculation shows how to find what is the difference between two fractions by subtracting a fraction 2/15 from 7/1. For different, unequal or unlike denominators, use any one of the following methods to find the equivalent fraction for 7/1 minus 2/15.
1. LCM method
2. Cross multiplication method.

(7/1) - (2/15) using LCM Method:
What is 7/1 minus 2/15 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 7/1
Fraction B: 2/15

What to be found?
(7/1) - (2/15) = ?
Find what's the difference between 7/1 and 2/15.

step 2 Compare the denominators of fractions 7/1 and 2/15 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 7/1 and 2/15 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 7/1 and 2/15:
The LCM of 1 and 15 is 15.

step 4 Write the fractions 7/1 and 2/15 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
= 7/1 - 2/15
= [(7 x 15)/(1 x 15)] - [(2 x 15)/(15 x 15)]

step 5 Simplify the expression to have common denominator:
= 105/15 - 2/15

step 6 Take the common values out and rewrite the above expression like the below:
= 1/15 x (105/1 - 2/1)
= 1/15 x (105 - 2)

step 7Simplify the above expression further:
= 1/15 x 103
= 103/15
7/1 - 2/15 = 103/15

Hence,
7/1 minus 2/15 as a fraction is 103/15.
