2. Cross multiplication method.

(15/4) - (11/10) using LCM Method:
What is 15/4 minus 11/10 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 15/4
Fraction B: 11/10

What to be found?
(15/4) - (11/10) = ?
Find what's the difference between 15/4 and 11/10.

step 2 Compare the denominators of fractions 15/4 and 11/10 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 15/4 and 11/10 are not equal, it is said to be unlike fractions subtraction.

The LCM of 4 and 10 is 20.

step 4 Write the fractions 15/4 and 11/10 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
= 15/4 - 11/10
= [(15 x 20)/(4 x 20)] - [(11 x 20)/(10 x 20)]

step 5 Simplify the expression to have common denominator:
= 75/20 - 22/20

step 6 Take the common values out and rewrite the above expression like the below:
= 1/20 x (75/1 - 22/1)
= 1/20 x (75 - 22)

step 7Simplify the above expression further:
= 1/20 x 53
= 53/20
15/4 - 11/10 = 53/20

Hence,
15/4 minus 11/10 as a fraction is 53/20.
