5 - 5/2 as a fraction

Learn how to find what is 5 minus 5/2 in fraction form just in a few minutes. We have covered the easiest method to write 5 - 5/2 as a fraction and decimal.

Summary: 5 minus 5/2 = 5/2
Since both fractions have unequal denominators, 5 minus 5/2 is an unlike fractions subtraction. For subtracting unlike fractions, you have to first find the equivalent fractions for fraction 5 and fraction 5/2 in order to have the same denominators for both fractions. Therefore, you have to find the LCM of denominators 1 and 2. 2 is the LCM of 1 and 2. Multiplying the LCM 2 with the numerators and denominators of both fractions (5 x 2/2) - (5/2 x 2/2), and simplify further in order to have the common denominator. So the equivalent fraction for 5 is 10/2 and for 5/2 is 5/2. By simplifying this fraction subtraction 10/2 - 5/2, it becomes 5/2.

CALCULATION: 5 - 5/2 as a fraction
5 - 5/2 = (?)
5/1 - 5/2 = [(5 x 2) - (5 x 1)]/(1 x 2)
= (10 - 5)/2
= 5/2
5 - 5/2 = 5/2
5 minus 5/2 as a fraction is 5/2.

where
5 is a whole number as a minuend,
5/2 is a improper fraction as a subtrahend,
5/2 is the difference between 5 and 5/2.

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

(5) - (5/2) using LCM Method:
What is 5 minus 5/2 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 5/1
Fraction B: 5/2

What to be found?
(5) - (5/2) = ?
Find what's the difference between 5 and 5/2.

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

step 4 Write the fractions 5 and 5/2 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
= 5 - 5/2
= [(5 x 2)/(1 x 2)] - [(5 x 2)/(2 x 2)]

step 5 Simplify the expression to have common denominator:
= 10/2 - 5/2

step 6 Take the common values out and rewrite the above expression like the below:
= 1/2 x (10/1 - 5/1)
= 1/2 x (10 - 5)

step 7Simplify the above expression further:
= 1/2 x 5
= 5/2
5 - 5/2 = 5/2

Hence,
5 minus 5/2 as a fraction is 5/2.

5 - 5/2 using Cross Multiplication Method:
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 5/1
Fraction B: 5/2

What to be found?
(5)-(5/2) = ?
Find what's the difference between 5 and 5/2.

step 2 Find the product of numerator of Fraction A and denominator of Fraction B (5 x 2), find the product of numerator of Fraction B and denominator of Fraction A (5 x 1), and find the product of both denominators of Fraction A and Fraction B (1 x 2) and rewrite the equation as like the below:
= (5 x 2) - (5 x 1)/(1 x 2)

step 3 Simplify and rewrite the fraction:
= (10 - 5)/2
5 - 5/2 = 5/2

Hence,
5 minus 5/2 in fraction is 5/2
