2. Cross multiplication method.

(15/2) + (17/5) using LCM Method:
What is 15/2 plus 17/5 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 15/2
Fraction B: 17/5

What to be found?
(15/2) + (17/5) = ?
Find what's the sum of 15/2 and 17/5.

step 2 Compare the denominators of fractions 15/2 and 17/5 to identify whether it is a like or unlike fraction addition. Since the denominators of given fractions 15/2 and 17/5 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 17/5:
The LCM of 2 and 5 is 10.

step 4 Write the fractions 15/2 and 17/5 in the addition expression form and multiply LCM with all the numerators and denominators of both fractions.
= 15/2 + 17/5
= [(15 x 10)/(2 x 10)] + [(17 x 10)/(5 x 10)]

step 5 Simplify the expression to have common denominator:
= 75/10 + 34/10

step 6 Take the common values out and rewrite the above expression like the below:
= 1/10 x (75/1 + 34/1)
= 1/10 x (75 + 34)

step 7Simplify the above expression further:
= 1/10 x 109
= 109/10
15/2 + 17/5 = 109/10

Hence,
15/2 plus 17/5 as a fraction is 109/10.
