2/4 - 1/90 as a fraction

Learn how to find what is 2/4 minus 1/90 in fraction form just in a few minutes. We have covered the easiest method to write 2/4 - 1/90 as a fraction and decimal.

Summary: 2/4 minus 1/90 = 22/45
Since both fractions have unequal denominators, 2/4 minus 1/90 is an unlike fractions subtraction. For subtracting unlike fractions, you have to first find the equivalent fractions for fraction 2/4 and fraction 1/90 in order to have the same denominators for both fractions. Therefore, you have to find the LCM of denominators 4 and 90. 180 is the LCM of 4 and 90. Multiplying the LCM 180 with the numerators and denominators of both fractions (2/4 x 180/180) - (1/90 x 180/180), and simplify further in order to have the common denominator. So the equivalent fraction for 2/4 is 90/180 and for 1/90 is 2/180. By simplifying this fraction subtraction 90/180 - 2/180, it becomes 88/180.

The below workout with step by step calculation shows how to find what is the difference between two fractions by subtracting a fraction 1/90 from 2/4. For different, unequal or unlike denominators, use any one of the following methods to find the equivalent fraction for 2/4 minus 1/90.
1. LCM method
2. Cross multiplication method.

(2/4) - (1/90) using LCM Method:
What is 2/4 minus 1/90 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 2/4
Fraction B: 1/90

What to be found?
(2/4) - (1/90) = ?
Find what's the difference between 2/4 and 1/90.

step 2 Compare the denominators of fractions 2/4 and 1/90 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 2/4 and 1/90 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 2/4 and 1/90:
The LCM of 4 and 90 is 180.

step 4 Write the fractions 2/4 and 1/90 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
= 2/4 - 1/90
= [(2 x 180)/(4 x 180)] - [(1 x 180)/(90 x 180)]

step 5 Simplify the expression to have common denominator:
= 90/180 - 2/180

step 6 Take the common values out and rewrite the above expression like the below:
= 1/180 x (90/1 - 2/1)
= 1/180 x (90 - 2)

step 7Simplify the above expression further:
= 1/180 x 88
= 88/180
= 22/45
2/4 - 1/90 = 22/45

Hence,
2/4 minus 1/90 as a fraction is 22/45.
