What is 9/8 minus 9/10 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 9/8
Fraction B: 9/10

What to be found?
9/8-9/10 = ?
Find what's the difference between 9/8 and 9/10.

step 2 Compare the denominators of fractions 9/8 and 9/10 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 9/8 and 9/10 are not equal, it is said to be unlike fractions subtraction.

The LCM of 8 and 10 is 40.

step 4 Write the fractions 9/8 and 9/10 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
=9/8-9/10
=(9 x 40)/(8 x 40)-(9 x 40)/(10 x 40)

step 5 Simplify the expression to have common denominator:
=45/40-36/40

step 6 Take the common values out and rewrite the above expression like the below:
=1/40 x (45/1-36/1)
=1/40 x (45 - 36)

step 7Simplify the above expression further:
=1/40 x 9
=9/40
9/8-9/10=9/40

Hence,
