1/2 - 1/77 as a fraction

Learn how to find what is 1/2 minus 1/77 in fraction form just in a few minutes. We have covered the easiest method to write 1/2 - 1/77 as a fraction and decimal.

Summary: 1/2 minus 1/77 = 75/154
Since both fractions have unequal denominators, 1/2 minus 1/77 is an unlike fractions subtraction. For subtracting unlike fractions, you have to first find the equivalent fractions for fraction 1/2 and fraction 1/77 in order to have the same denominators for both fractions. Therefore, you have to find the LCM of denominators 2 and 77. 154 is the LCM of 2 and 77. Multiplying the LCM 154 with the numerators and denominators of both fractions (1/2 x 154/154) - (1/77 x 154/154), and simplify further in order to have the common denominator. So the equivalent fraction for 1/2 is 77/154 and for 1/77 is 2/154. By simplifying this fraction subtraction 77/154 - 2/154, it becomes 75/154.

The below workout with step by step calculation shows how to find what is the difference between two fractions by subtracting a fraction 1/77 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 1/77.
1. LCM method
2. Cross multiplication method.

(1/2) - (1/77) using LCM Method:
What is 1/2 minus 1/77 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 1/2
Fraction B: 1/77

What to be found?
(1/2) - (1/77) = ?
Find what's the difference between 1/2 and 1/77.

step 2 Compare the denominators of fractions 1/2 and 1/77 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 1/2 and 1/77 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 1/77:
The LCM of 2 and 77 is 154.

step 4 Write the fractions 1/2 and 1/77 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
= 1/2 - 1/77
= [(1 x 154)/(2 x 154)] - [(1 x 154)/(77 x 154)]

step 5 Simplify the expression to have common denominator:
= 77/154 - 2/154

step 6 Take the common values out and rewrite the above expression like the below:
= 1/154 x (77/1 - 2/1)
= 1/154 x (77 - 2)

step 7Simplify the above expression further:
= 1/154 x 75
= 75/154
1/2 - 1/77 = 75/154

Hence,
1/2 minus 1/77 as a fraction is 75/154.
