Learn how to find what is 2/5 minus 1/2 in fraction form just in a few minutes. We have covered the easiest method to write 2/5 - 1/2 as a fraction and decimal.
Summary: 2/5 minus 1/2
Since both the fractions have the unequal denominators, you have to find the equivalent fractions for 2/5 and 1/2 having identical denominators before starting adding the fractions. Find the LCM of denominators, 10 is the LCM of 5 and 2. Multiply the LCM 10 with all the numerators and denominators of both fractions (2/5 x 10/10) - (1/2 x 10/10) and simplify further in order to have the common denominators. By simplifying the fraction subtraction expression becomes -1/10.
The below workout with step by step calculation shows how to find what is the difference between two fractions by subtracting a fraction 1/2 from 2/5. For different, unequal or unlike denominators, use any one of the following methods to find the equivalent fraction for 2/5 minus 1/2.
1. LCM method
2. Cross multiplication method.
2/5-1/2 using LCM Method:
What is 2/5 minus 1/2 as a fraction?
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 2/5
Fraction B: 1/2
What to be found?
2/5-1/2 = ?
Find what's the difference between 2/5 and 1/2.
step 2 Compare the denominators of fractions 2/5 and 1/2 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 2/5 and 1/2 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 2/5 and 1/2:
The LCM of 5 and 2 is 10.
step 4 Write the fractions 2/5 and 1/2 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
=2/5-1/2
=(2 x 10)/(5 x 10)-(1 x 10)/(2 x 10)
step 5 Simplify the expression to have common denominator:
=4/10-5/10
step 6 Take the common values out and rewrite the above expression like the below:
=1/10 x (4/1-5/1)
=1/10 x (4 - 5)
step 7Simplify the above expression further:
=1/10 x -1
=-1/10
2/5-1/2=-1/10
Hence,
2/5 minus 1/2 equals to -1/10 in fraction.
2/5-1/2 using Cross Multiplication Method:
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 2/5
Fraction B: 1/2
What to be found?
2/5-1/2 = ?
Find what's the difference between 2/5 and 1/2.
step 2 Find the product of numerator of Fraction A and denominator of Fraction B (2 x 2), find the product of numerator of Fraction B and denominator of Fraction A (1 x 5), and find the product of both denominators of Fraction A and Fraction B (5 x 2) and rewrite the equation as like the below:
= (2 x 2) - (1 x 5)/(5 x 2)
step 3 Simplify and rewrite the fraction:
= (4 - 5)/10
2/5-1/2 = -1/10
Hence,
2/5 minus 1/2 = -1/10
