(9/4) - (11/5) using LCM Method:
What is 9/4 minus 11/5 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 9/4
Fraction B: 11/5

What to be found?
(9/4) - (11/5) = ?
Find what's the difference between 9/4 and 11/5.

step 2 Compare the denominators of fractions 9/4 and 11/5 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 9/4 and 11/5 are not equal, it is said to be unlike fractions subtraction.

The LCM of 4 and 5 is 20.

step 4 Write the fractions 9/4 and 11/5 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
= 9/4 - 11/5
= [(9 x 20)/(4 x 20)] - [(11 x 20)/(5 x 20)]

step 5 Simplify the expression to have common denominator:
= 45/20 - 44/20

step 6 Take the common values out and rewrite the above expression like the below:
= 1/20 x (45/1 - 44/1)
= 1/20 x (45 - 44)

step 7Simplify the above expression further:
= 1/20 x 1
= 1/20
9/4 - 11/5 = 1/20

Hence,
9/4 minus 11/5 as a fraction is 1/20.
