Learn how to find what is 1/1 minus 1/79 in fraction form just in a few minutes. We have covered the easiest method to write 1/1 - 1/79 as a fraction and decimal.

Summary: 1/1 minus 1/79 = 78/79
Since both fractions have unequal denominators, 1/1 minus 1/79 is an unlike fractions subtraction. For subtracting unlike fractions, you have to first find the equivalent fractions for fraction 1/1 and fraction 1/79 in order to have the same denominators for both fractions. Therefore, you have to find the LCM of denominators 1 and 79. 79 is the LCM of 1 and 79. Multiplying the LCM 79 with the numerators and denominators of both fractions (1/1 x 79/79) - (1/79 x 79/79), and simplify further in order to have the common denominator. So the equivalent fraction for 1/1 is 79/79 and for 1/79 is 1/79. By simplifying this fraction subtraction 79/79 - 1/79, it becomes 78/79.

The below workout with step by step calculation shows how to find what is the difference between two fractions by subtracting a fraction 1/79 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 1/79.
1. LCM method
2. Cross multiplication method.

(1/1) - (1/79) using LCM Method:
What is 1/1 minus 1/79 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 1/1
Fraction B: 1/79

What to be found?
(1/1) - (1/79) = ?
Find what's the difference between 1/1 and 1/79.

step 2 Compare the denominators of fractions 1/1 and 1/79 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 1/1 and 1/79 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 1/79:
The LCM of 1 and 79 is 79.

step 4 Write the fractions 1/1 and 1/79 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
= 1/1 - 1/79
= [(1 x 79)/(1 x 79)] - [(1 x 79)/(79 x 79)]

step 5 Simplify the expression to have common denominator:
= 79/79 - 1/79

step 6 Take the common values out and rewrite the above expression like the below:
= 1/79 x (79/1 - 1/1)
= 1/79 x (79 - 1)

step 7Simplify the above expression further:
= 1/79 x 78
= 78/79
1/1 - 1/79 = 78/79

Hence,
1/1 minus 1/79 as a fraction is 78/79.

1/1 - 1/79 using Cross Multiplication Method:
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 1/1
Fraction B: 1/79

What to be found?
(1/1)-(1/79) = ?
Find what's the difference between 1/1 and 1/79.

step 2 Find the product of numerator of Fraction A and denominator of Fraction B (1 x 79), find the product of numerator of Fraction B and denominator of Fraction A (1 x 1), and find the product of both denominators of Fraction A and Fraction B (1 x 79) and rewrite the equation as like the below:
= (1 x 79) - (1 x 1)/(1 x 79)

step 3 Simplify and rewrite the fraction:
= (79 - 1)/79
