7/2 - 11 as a fraction

Learn how to find what is 7/2 minus 11 in fraction form just in a few minutes. We have covered the easiest method to write 7/2 - 11 as a fraction and decimal.

Summary: 7/2 minus 11 = -15/2
Since both fractions have unequal denominators, 7/2 minus 11 is an unlike fractions subtraction. For subtracting unlike fractions, you have to first find the equivalent fractions for fraction 7/2 and fraction 11 in order to have the same denominators for both fractions. Therefore, you have to find the LCM of denominators 2 and 1. 2 is the LCM of 2 and 1. Multiplying the LCM 2 with the numerators and denominators of both fractions (7/2 x 2/2) - (11 x 2/2), and simplify further in order to have the common denominator. So the equivalent fraction for 7/2 is 7/2 and for 11 is 22/2. By simplifying this fraction subtraction 7/2 - 22/2, it becomes -15/2.

CALCULATION: 7/2 - 11 as a fraction

2. Cross multiplication method.

(7/2) - (11) using LCM Method:
What is 7/2 minus 11 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 7/2
Fraction B: 11/1

What to be found?
(7/2) - (11) = ?
Find what's the difference between 7/2 and 11.

step 2 Compare the denominators of fractions 7/2 and 11 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 7/2 and 11 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 7/2 and 11:
The LCM of 2 and 1 is 2.

step 4 Write the fractions 7/2 and 11 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
= 7/2 - 11
= [(7 x 2)/(2 x 2)] - [(11 x 2)/(1 x 2)]

step 5 Simplify the expression to have common denominator:
= 7/2 - 22/2

step 6 Take the common values out and rewrite the above expression like the below:
= 1/2 x (7/1 - 22/1)
= 1/2 x (7 - 22)

step 7Simplify the above expression further:
= 1/2 x -15
= -15/2
7/2 - 11 = -15/2

Hence,
7/2 minus 11 as a fraction is -15/2.
