Learn how to find what is 1/2 minus 2/11 in fraction form just in a few minutes. We have covered the easiest method to write 1/2 - 2/11 as a fraction and decimal.
Summary: 1/2 minus 2/11
Since both the fractions have the unequal denominators, you have to find the equivalent fractions for 1/2 and 2/11 having identical denominators before starting adding the fractions. Find the LCM of denominators, 22 is the LCM of 2 and 11. Multiply the LCM 22 with all the numerators and denominators of both fractions (1/2 x 22/22) - (2/11 x 22/22) and simplify further in order to have the common denominators. By simplifying the fraction subtraction expression becomes 7/22.
The below workout with step by step calculation shows how to find what is the difference between two fractions by subtracting a fraction 2/11 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 2/11.
1. LCM method
2. Cross multiplication method.
1/2-2/11 using LCM Method:
What is 1/2 minus 2/11 as a fraction?
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 1/2
Fraction B: 2/11
What to be found?
1/2-2/11 = ?
Find what's the difference between 1/2 and 2/11.
step 2 Compare the denominators of fractions 1/2 and 2/11 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 1/2 and 2/11 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 2/11:
The LCM of 2 and 11 is 22.
step 4 Write the fractions 1/2 and 2/11 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
=1/2-2/11
=(1 x 22)/(2 x 22)-(2 x 22)/(11 x 22)
step 5 Simplify the expression to have common denominator:
=11/22-4/22
step 6 Take the common values out and rewrite the above expression like the below:
=1/22 x (11/1-4/1)
=1/22 x (11 - 4)
step 7Simplify the above expression further:
=1/22 x 7
=7/22
1/2-2/11=7/22
Hence,
1/2 minus 2/11 equals to 7/22 in fraction.
1/2-2/11 using Cross Multiplication Method:
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 1/2
Fraction B: 2/11
What to be found?
1/2-2/11 = ?
Find what's the difference between 1/2 and 2/11.
step 2 Find the product of numerator of Fraction A and denominator of Fraction B (1 x 11), find the product of numerator of Fraction B and denominator of Fraction A (2 x 2), and find the product of both denominators of Fraction A and Fraction B (2 x 11) and rewrite the equation as like the below:
= (1 x 11) - (2 x 2)/(2 x 11)
step 3 Simplify and rewrite the fraction:
= (11 - 4)/22
1/2-2/11 = 7/22
Hence,
1/2 minus 2/11 = 7/22
