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

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

What to be found?
(15/2) + (17/4) = ?
Find what's the sum of 15/2 and 17/4.

step 2 Compare the denominators of fractions 15/2 and 17/4 to identify whether it is a like or unlike fraction addition. Since the denominators of given fractions 15/2 and 17/4 are not equal, it is said to be unlike fractions addition.

step 3For unlike fractions addition, find the LCM (least common multiple) of both denominators of fractions 15/2 and 17/4:
The LCM of 2 and 4 is 4.

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

step 5 Simplify the expression to have common denominator:
= 30/4 + 17/4

step 6 Take the common values out and rewrite the above expression like the below:
= 1/4 x (30/1 + 17/1)
= 1/4 x (30 + 17)

step 7Simplify the above expression further:
= 1/4 x 47
= 47/4
15/2 + 17/4 = 47/4

Hence,
15/2 plus 17/4 as a fraction is 47/4.
