1/2 - 1/80 as a fraction

Learn how to find what is 1/2 minus 1/80 in fraction form just in a few minutes. We have covered the easiest method to write 1/2 - 1/80 as a fraction and decimal.

Summary: 1/2 minus 1/80 = 39/80
Since both fractions have unequal denominators, 1/2 minus 1/80 is an unlike fractions subtraction. For subtracting unlike fractions, you have to first find the equivalent fractions for fraction 1/2 and fraction 1/80 in order to have the same denominators for both fractions. Therefore, you have to find the LCM of denominators 2 and 80. 80 is the LCM of 2 and 80. Multiplying the LCM 80 with the numerators and denominators of both fractions (1/2 x 80/80) - (1/80 x 80/80), and simplify further in order to have the common denominator. So the equivalent fraction for 1/2 is 40/80 and for 1/80 is 1/80. By simplifying this fraction subtraction 40/80 - 1/80, it becomes 39/80.

The below workout with step by step calculation shows how to find what is the difference between two fractions by subtracting a fraction 1/80 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 1/80.
1. LCM method
2. Cross multiplication method.

(1/2) - (1/80) using LCM Method:
What is 1/2 minus 1/80 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 1/2
Fraction B: 1/80

What to be found?
(1/2) - (1/80) = ?
Find what's the difference between 1/2 and 1/80.

step 2 Compare the denominators of fractions 1/2 and 1/80 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 1/2 and 1/80 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 1/80:
The LCM of 2 and 80 is 80.

step 4 Write the fractions 1/2 and 1/80 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
= 1/2 - 1/80
= [(1 x 80)/(2 x 80)] - [(1 x 80)/(80 x 80)]

step 5 Simplify the expression to have common denominator:
= 40/80 - 1/80

step 6 Take the common values out and rewrite the above expression like the below:
= 1/80 x (40/1 - 1/1)
= 1/80 x (40 - 1)

step 7Simplify the above expression further:
= 1/80 x 39
= 39/80
1/2 - 1/80 = 39/80

Hence,
1/2 minus 1/80 as a fraction is 39/80.

1/2 - 1/80 using Cross Multiplication Method:
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 1/2
Fraction B: 1/80

What to be found?
(1/2)-(1/80) = ?
Find what's the difference between 1/2 and 1/80.

step 2 Find the product of numerator of Fraction A and denominator of Fraction B (1 x 80), find the product of numerator of Fraction B and denominator of Fraction A (1 x 2), and find the product of both denominators of Fraction A and Fraction B (2 x 80) and rewrite the equation as like the below:
= (1 x 80) - (1 x 2)/(2 x 80)

step 3 Simplify and rewrite the fraction:
= (80 - 2)/160
= 78/160
= 39/80
1/2 - 1/80 = 39/80

Hence,
1/2 minus 1/80 in fraction is 39/80
