1/2 minus 3/12 equals to 1/4 in fraction form.
Learn how to find what is 1/2 minus 3/12 in fraction form just in a few minutes. We have covered the easiest method to write 1/2 - 3/12 as a fraction and decimal.
Summary: 1/2 minus 3/12
Since both the fractions have the unequal denominators, you have to find the equivalent fractions for 1/2 and 3/12 having identical denominators before starting adding the fractions. Find the LCM of denominators, 12 is the LCM of 2 and 12. Multiply the LCM 12 with all the numerators and denominators of both fractions (1/2 x 12/12) - (3/12 x 12/12) and simplify further in order to have the common denominators. By simplifying the fraction subtraction expression becomes 3/12.
The below workout with step by step calculation shows how to find what is the difference between two fractions by subtracting a fraction 3/12 from 1/2. For different, unequal or unlike denominators, use any one of the following methods to find the equivalent fraction for 1/2 minus 3/12.
1. LCM method
2. Cross multiplication method.
1/2-3/12 using LCM Method:
What is 1/2 minus 3/12 as a fraction?
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 1/2
Fraction B: 3/12
What to be found?
1/2-3/12 = ?
Find what's the difference between 1/2 and 3/12.
step 2 Compare the denominators of fractions 1/2 and 3/12 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 1/2 and 3/12 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 1/2 and 3/12:
The LCM of 2 and 12 is 12.
step 4 Write the fractions 1/2 and 3/12 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
=1/2-3/12
=(1 x 12)/(2 x 12)-(3 x 12)/(12 x 12)
step 5 Simplify the expression to have common denominator:
=6/12-3/12
step 6 Take the common values out and rewrite the above expression like the below:
=1/12 x (6/1-3/1)
=1/12 x (6 - 3)
step 7Simplify the above expression further:
=1/12 x 3
= 3/12
=1/4
1/2-3/12=1/4
Hence,
1/2 minus 3/12 equals to 1/4 in fraction.
1/2-3/12 using Cross Multiplication Method:
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 1/2
Fraction B: 3/12
What to be found?
1/2-3/12 = ?
Find what's the difference between 1/2 and 3/12.
step 2 Find the product of numerator of Fraction A and denominator of Fraction B (1 x 12), find the product of numerator of Fraction B and denominator of Fraction A (3 x 2), and find the product of both denominators of Fraction A and Fraction B (2 x 12) and rewrite the equation as like the below:
= (1 x 12) - (3 x 2)/(2 x 12)
step 3 Simplify and rewrite the fraction:
= (12 - 6)/24
= 6/24
= 1/4
1/2-3/12 = 1/4
Hence,
1/2 minus 3/12 = 1/4
