Learn how to find what is 1/1 minus 1/99 in fraction form just in a few minutes. We have covered the easiest method to write 1/1 - 1/99 as a fraction and decimal.

Summary: 1/1 minus 1/99 = 98/99
Since both fractions have unequal denominators, 1/1 minus 1/99 is an unlike fractions subtraction. For subtracting unlike fractions, you have to first find the equivalent fractions for fraction 1/1 and fraction 1/99 in order to have the same denominators for both fractions. Therefore, you have to find the LCM of denominators 1 and 99. 99 is the LCM of 1 and 99. Multiplying the LCM 99 with the numerators and denominators of both fractions (1/1 x 99/99) - (1/99 x 99/99), and simplify further in order to have the common denominator. So the equivalent fraction for 1/1 is 99/99 and for 1/99 is 1/99. By simplifying this fraction subtraction 99/99 - 1/99, it becomes 98/99.

The below workout with step by step calculation shows how to find what is the difference between two fractions by subtracting a fraction 1/99 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 1/99.
1. LCM method
2. Cross multiplication method.

(1/1) - (1/99) using LCM Method:
What is 1/1 minus 1/99 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 1/1
Fraction B: 1/99

What to be found?
(1/1) - (1/99) = ?
Find what's the difference between 1/1 and 1/99.

step 2 Compare the denominators of fractions 1/1 and 1/99 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 1/1 and 1/99 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 1/99:
The LCM of 1 and 99 is 99.

step 4 Write the fractions 1/1 and 1/99 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
= 1/1 - 1/99
= [(1 x 99)/(1 x 99)] - [(1 x 99)/(99 x 99)]

step 5 Simplify the expression to have common denominator:
= 99/99 - 1/99

step 6 Take the common values out and rewrite the above expression like the below:
= 1/99 x (99/1 - 1/1)
= 1/99 x (99 - 1)

step 7Simplify the above expression further:
= 1/99 x 98
= 98/99
1/1 - 1/99 = 98/99

Hence,
1/1 minus 1/99 as a fraction is 98/99.

1/1 - 1/99 using Cross Multiplication Method:
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 1/1
Fraction B: 1/99

What to be found?
(1/1)-(1/99) = ?
Find what's the difference between 1/1 and 1/99.

step 2 Find the product of numerator of Fraction A and denominator of Fraction B (1 x 99), 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 99) and rewrite the equation as like the below:
= (1 x 99) - (1 x 1)/(1 x 99)

step 3 Simplify and rewrite the fraction:
= (99 - 1)/99
