1/2 - 2/72 as a fraction

Learn how to find what is 1/2 minus 2/72 in fraction form just in a few minutes. We have covered the easiest method to write 1/2 - 2/72 as a fraction and decimal.

Summary: 1/2 minus 2/72 = 17/36
Since both fractions have unequal denominators, 1/2 minus 2/72 is an unlike fractions subtraction. For subtracting unlike fractions, you have to first find the equivalent fractions for fraction 1/2 and fraction 2/72 in order to have the same denominators for both fractions. Therefore, you have to find the LCM of denominators 2 and 72. 72 is the LCM of 2 and 72. Multiplying the LCM 72 with the numerators and denominators of both fractions (1/2 x 72/72) - (2/72 x 72/72), and simplify further in order to have the common denominator. So the equivalent fraction for 1/2 is 36/72 and for 2/72 is 2/72. By simplifying this fraction subtraction 36/72 - 2/72, it becomes 34/72.

The below workout with step by step calculation shows how to find what is the difference between two fractions by subtracting a fraction 2/72 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 2/72.
1. LCM method
2. Cross multiplication method.

(1/2) - (2/72) using LCM Method:
What is 1/2 minus 2/72 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 1/2
Fraction B: 2/72

What to be found?
(1/2) - (2/72) = ?
Find what's the difference between 1/2 and 2/72.

step 2 Compare the denominators of fractions 1/2 and 2/72 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 1/2 and 2/72 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 2/72:
The LCM of 2 and 72 is 72.

step 4 Write the fractions 1/2 and 2/72 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
= 1/2 - 2/72
= [(1 x 72)/(2 x 72)] - [(2 x 72)/(72 x 72)]

step 5 Simplify the expression to have common denominator:
= 36/72 - 2/72

step 6 Take the common values out and rewrite the above expression like the below:
= 1/72 x (36/1 - 2/1)
= 1/72 x (36 - 2)

step 7Simplify the above expression further:
= 1/72 x 34
= 34/72
= 17/36
1/2 - 2/72 = 17/36

Hence,
1/2 minus 2/72 as a fraction is 17/36.

1/2 - 2/72 using Cross Multiplication Method:
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 1/2
Fraction B: 2/72

What to be found?
(1/2)-(2/72) = ?
Find what's the difference between 1/2 and 2/72.

step 2 Find the product of numerator of Fraction A and denominator of Fraction B (1 x 72), 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 72) and rewrite the equation as like the below:
= (1 x 72) - (2 x 2)/(2 x 72)

step 3 Simplify and rewrite the fraction:
= (72 - 4)/144
= 68/144
= 17/36
