1/1 - 2/80 as a fraction

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

Summary: 1/1 minus 2/80 = 39/40
Since both fractions have unequal denominators, 1/1 minus 2/80 is an unlike fractions subtraction. For subtracting unlike fractions, you have to first find the equivalent fractions for fraction 1/1 and fraction 2/80 in order to have the same denominators for both fractions. Therefore, you have to find the LCM of denominators 1 and 80. 80 is the LCM of 1 and 80. Multiplying the LCM 80 with the numerators and denominators of both fractions (1/1 x 80/80) - (2/80 x 80/80), and simplify further in order to have the common denominator. So the equivalent fraction for 1/1 is 80/80 and for 2/80 is 2/80. By simplifying this fraction subtraction 80/80 - 2/80, it becomes 78/80.

The below workout with step by step calculation shows how to find what is the difference between two fractions by subtracting a fraction 2/80 from 1/1. For different, unequal or unlike denominators, use any one of the following methods to find the equivalent fraction for 1/1 minus 2/80.
1. LCM method
2. Cross multiplication method.

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

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

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

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

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

step 5 Simplify the expression to have common denominator:
= 80/80 - 2/80

step 6 Take the common values out and rewrite the above expression like the below:
= 1/80 x (80/1 - 2/1)
= 1/80 x (80 - 2)

step 7Simplify the above expression further:
= 1/80 x 78
= 78/80
= 39/40
1/1 - 2/80 = 39/40

Hence,
1/1 minus 2/80 as a fraction is 39/40.

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

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

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

step 3 Simplify and rewrite the fraction:
= (80 - 2)/80
= 78/80
= 39/40
1/1 - 2/80 = 39/40

Hence,
1/1 minus 2/80 in fraction is 39/40
