7/2 - 10 as a fraction

Learn how to find what is 7/2 minus 10 in fraction form just in a few minutes. We have covered the easiest method to write 7/2 - 10 as a fraction and decimal.

Summary: 7/2 minus 10 = -13/2
Since both fractions have unequal denominators, 7/2 minus 10 is an unlike fractions subtraction. For subtracting unlike fractions, you have to first find the equivalent fractions for fraction 7/2 and fraction 10 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) - (10 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 10 is 20/2. By simplifying this fraction subtraction 7/2 - 20/2, it becomes -13/2.

CALCULATION: 7/2 - 10 as a fraction

The below workout with step by step calculation shows how to find the difference between fraction and a whole number by subtracting 10 from 7/2. use any one of the following methods to find the equivalent fraction for 7/2 minus 10.
1. LCM method
2. Cross multiplication method.

(7/2) - (10) using LCM Method:
What is 7/2 minus 10 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 7/2
Fraction B: 10/1

What to be found?
(7/2) - (10) = ?
Find what's the difference between 7/2 and 10.

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

step 4 Write the fractions 7/2 and 10 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
= 7/2 - 10
= [(7 x 2)/(2 x 2)] - [(10 x 2)/(1 x 2)]

step 5 Simplify the expression to have common denominator:
= 7/2 - 20/2

step 6 Take the common values out and rewrite the above expression like the below:
= 1/2 x (7/1 - 20/1)
= 1/2 x (7 - 20)

step 7Simplify the above expression further:
= 1/2 x -13
= -13/2
7/2 - 10 = -13/2

Hence,
7/2 minus 10 as a fraction is -13/2.

7/2 - 10 using Cross Multiplication Method:
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 7/2
Fraction B: 10/1

What to be found?
(7/2)-(10) = ?
Find what's the difference between 7/2 and 10.

step 2 Find the product of numerator of Fraction A and denominator of Fraction B (7 x 1), find the product of numerator of Fraction B and denominator of Fraction A (10 x 2), and find the product of both denominators of Fraction A and Fraction B (2 x 1) and rewrite the equation as like the below:
= (7 x 1) - (10 x 2)/(2 x 1)

step 3 Simplify and rewrite the fraction:
= (7 - 20)/2
7/2 - 10 = -13/2

Hence,
