2. Cross multiplication method.

(17/2) - (15/4) using LCM Method:
What is 17/2 minus 15/4 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 17/2
Fraction B: 15/4

What to be found?
(17/2) - (15/4) = ?
Find what's the difference between 17/2 and 15/4.

step 2 Compare the denominators of fractions 17/2 and 15/4 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 17/2 and 15/4 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 17/2 and 15/4:
The LCM of 2 and 4 is 4.

step 4 Write the fractions 17/2 and 15/4 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
= 17/2 - 15/4
= [(17 x 4)/(2 x 4)] - [(15 x 4)/(4 x 4)]

step 5 Simplify the expression to have common denominator:
= 34/4 - 15/4

step 6 Take the common values out and rewrite the above expression like the below:
= 1/4 x (34/1 - 15/1)
= 1/4 x (34 - 15)

step 7Simplify the above expression further:
= 1/4 x 19
= 19/4
17/2 - 15/4 = 19/4

Hence,
17/2 minus 15/4 as a fraction is 19/4.
