2. Cross multiplication method.

(15/4) - (13/6) using LCM Method:
What is 15/4 minus 13/6 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 15/4
Fraction B: 13/6

What to be found?
(15/4) - (13/6) = ?
Find what's the difference between 15/4 and 13/6.

step 2 Compare the denominators of fractions 15/4 and 13/6 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 15/4 and 13/6 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 15/4 and 13/6:
The LCM of 4 and 6 is 12.

step 4 Write the fractions 15/4 and 13/6 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
= 15/4 - 13/6
= [(15 x 12)/(4 x 12)] - [(13 x 12)/(6 x 12)]

step 5 Simplify the expression to have common denominator:
= 45/12 - 26/12

step 6 Take the common values out and rewrite the above expression like the below:
= 1/12 x (45/1 - 26/1)
= 1/12 x (45 - 26)

step 7Simplify the above expression further:
= 1/12 x 19
= 19/12
15/4 - 13/6 = 19/12

Hence,
15/4 minus 13/6 as a fraction is 19/12.
