(4/5) + (9/17) using LCM Method:
What is 4/5 plus 9/17 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 4/5
Fraction B: 9/17

What to be found?
(4/5) + (9/17) = ?
Find what's the sum of 4/5 and 9/17.

step 2 Compare the denominators of fractions 4/5 and 9/17 to identify whether it is a like or unlike fraction addition. Since the denominators of given fractions 4/5 and 9/17 are not equal, it is said to be unlike fractions addition.

step 4 Write the fractions 4/5 and 9/17 in the addition expression form and multiply LCM with all the numerators and denominators of both fractions.
= 4/5 + 9/17
= [(4 x 85)/(5 x 85)] + [(9 x 85)/(17 x 85)]

step 5 Simplify the expression to have common denominator:
= 68/85 + 45/85

step 6 Take the common values out and rewrite the above expression like the below:
= 1/85 x (68/1 + 45/1)
= 1/85 x (68 + 45)

step 7Simplify the above expression further:
= 1/85 x 113
= 113/85
4/5 + 9/17 = 113/85
