(7/2) + (15/17) using LCM Method:
What is 7/2 plus 15/17 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 7/2
Fraction B: 15/17

What to be found?
(7/2) + (15/17) = ?
Find what's the sum of 7/2 and 15/17.

step 2 Compare the denominators of fractions 7/2 and 15/17 to identify whether it is a like or unlike fraction addition. Since the denominators of given fractions 7/2 and 15/17 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 7/2 and 15/17:
The LCM of 2 and 17 is 34.

step 4 Write the fractions 7/2 and 15/17 in the addition expression form and multiply LCM with all the numerators and denominators of both fractions.
= 7/2 + 15/17
= [(7 x 34)/(2 x 34)] + [(15 x 34)/(17 x 34)]

step 5 Simplify the expression to have common denominator:
= 119/34 + 30/34

step 6 Take the common values out and rewrite the above expression like the below:
= 1/34 x (119/1 + 30/1)
= 1/34 x (119 + 30)

step 7Simplify the above expression further:
= 1/34 x 149
= 149/34
7/2 + 15/17 = 149/34

Hence,
7/2 plus 15/17 as a fraction is 149/34.
