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 2/8. For different, unequal or unlike denominators, use any one of the following methods to find the equivalent fraction for 2/8 minus 1/90.
1. LCM method
2. Cross multiplication method.

(2/8) - (1/90) using LCM Method:
What is 2/8 minus 1/90 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 2/8
Fraction B: 1/90

What to be found?
(2/8) - (1/90) = ?
Find what's the difference between 2/8 and 1/90.

step 2 Compare the denominators of fractions 2/8 and 1/90 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 2/8 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 2/8 and 1/90:
The LCM of 8 and 90 is 360.

step 4 Write the fractions 2/8 and 1/90 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
= 2/8 - 1/90
= [(2 x 360)/(8 x 360)] - [(1 x 360)/(90 x 360)]

step 5 Simplify the expression to have common denominator:
= 90/360 - 4/360

step 6 Take the common values out and rewrite the above expression like the below:
= 1/360 x (90/1 - 4/1)
= 1/360 x (90 - 4)

step 7Simplify the above expression further:
= 1/360 x 86
= 86/360
= 43/180
2/8 - 1/90 = 43/180

Hence,
2/8 minus 1/90 as a fraction is 43/180.
