7/2 - 7/4 as a fraction

Learn how to find what is 7/2 minus 7/4 in fraction form just in a few minutes. We have covered the easiest method to write 7/2 - 7/4 as a fraction and decimal.

Summary: 7/2 minus 7/4 = 7/4
Since both fractions have unequal denominators, 7/2 minus 7/4 is an unlike fractions subtraction. For subtracting unlike fractions, you have to first find the equivalent fractions for fraction 7/2 and fraction 7/4 in order to have the same denominators for both fractions. Therefore, you have to find the LCM of denominators 2 and 4. 4 is the LCM of 2 and 4. Multiplying the LCM 4 with the numerators and denominators of both fractions (7/2 x 4/4) - (7/4 x 4/4), and simplify further in order to have the common denominator. So the equivalent fraction for 7/2 is 14/4 and for 7/4 is 7/4. By simplifying this fraction subtraction 14/4 - 7/4, it becomes 7/4.

CALCULATION: 7/2 - 7/4 as a fraction

The below workout with step by step calculation shows how to find what is the difference between two fractions by subtracting a fraction 7/4 from 7/2. For different, unequal or unlike denominators, use any one of the following methods to find the equivalent fraction for 7/2 minus 7/4.
1. LCM method
2. Cross multiplication method.

(7/2) - (7/4) using LCM Method:
What is 7/2 minus 7/4 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 7/2
Fraction B: 7/4

What to be found?
(7/2) - (7/4) = ?
Find what's the difference between 7/2 and 7/4.

step 2 Compare the denominators of fractions 7/2 and 7/4 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 7/2 and 7/4 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 7/4:
The LCM of 2 and 4 is 4.

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

step 5 Simplify the expression to have common denominator:
= 14/4 - 7/4

step 6 Take the common values out and rewrite the above expression like the below:
= 1/4 x (14/1 - 7/1)
= 1/4 x (14 - 7)

step 7Simplify the above expression further:
= 1/4 x 7
= 7/4
7/2 - 7/4 = 7/4

Hence,
7/2 minus 7/4 as a fraction is 7/4.

7/2 - 7/4 using Cross Multiplication Method:
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 7/2
Fraction B: 7/4

What to be found?
(7/2)-(7/4) = ?
Find what's the difference between 7/2 and 7/4.

step 2 Find the product of numerator of Fraction A and denominator of Fraction B (7 x 4), find the product of numerator of Fraction B and denominator of Fraction A (7 x 2), and find the product of both denominators of Fraction A and Fraction B (2 x 4) and rewrite the equation as like the below:
= (7 x 4) - (7 x 2)/(2 x 4)

step 3 Simplify and rewrite the fraction:
= (28 - 14)/8
= 14/8
= 7/4
7/2 - 7/4 = 7/4

Hence,
7/2 minus 7/4 in fraction is 7/4
