(9/7) + (1/15) using LCM Method:
What is 9/7 plus 1/15 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 9/7
Fraction B: 1/15

What to be found?
(9/7) + (1/15) = ?
Find what's the sum of 9/7 and 1/15.

step 2 Compare the denominators of fractions 9/7 and 1/15 to identify whether it is a like or unlike fraction addition. Since the denominators of given fractions 9/7 and 1/15 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 9/7 and 1/15:
The LCM of 7 and 15 is 105.

step 4 Write the fractions 9/7 and 1/15 in the addition expression form and multiply LCM with all the numerators and denominators of both fractions.
= 9/7 + 1/15
= [(9 x 105)/(7 x 105)] + [(1 x 105)/(15 x 105)]

step 5 Simplify the expression to have common denominator:
= 135/105 + 7/105

step 6 Take the common values out and rewrite the above expression like the below:
= 1/105 x (135/1 + 7/1)
= 1/105 x (135 + 7)

step 7Simplify the above expression further:
= 1/105 x 142
= 142/105
9/7 + 1/15 = 142/105
