The below workout with step by step calculation shows how to find what is the difference between two fractions by subtracting a fraction 2/45 from 1/8. For different, unequal or unlike denominators, use any one of the following methods to find the equivalent fraction for 1/8 minus 2/45.
1. LCM method
2. Cross multiplication method.

(1/8) - (2/45) using LCM Method:
What is 1/8 minus 2/45 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 1/8
Fraction B: 2/45

What to be found?
(1/8) - (2/45) = ?
Find what's the difference between 1/8 and 2/45.

step 2 Compare the denominators of fractions 1/8 and 2/45 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 1/8 and 2/45 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 1/8 and 2/45:
The LCM of 8 and 45 is 360.

step 4 Write the fractions 1/8 and 2/45 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
= 1/8 - 2/45
= [(1 x 360)/(8 x 360)] - [(2 x 360)/(45 x 360)]

step 5 Simplify the expression to have common denominator:
= 45/360 - 16/360

step 6 Take the common values out and rewrite the above expression like the below:
= 1/360 x (45/1 - 16/1)
= 1/360 x (45 - 16)

step 7Simplify the above expression further:
= 1/360 x 29
= 29/360
1/8 - 2/45 = 29/360

Hence,
1/8 minus 2/45 as a fraction is 29/360.
