(17/2) + (7/20) using LCM Method:
What is 17/2 plus 7/20 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 17/2
Fraction B: 7/20

What to be found?
(17/2) + (7/20) = ?
Find what's the sum of 17/2 and 7/20.

step 2 Compare the denominators of fractions 17/2 and 7/20 to identify whether it is a like or unlike fraction addition. Since the denominators of given fractions 17/2 and 7/20 are not equal, it is said to be unlike fractions addition.

The LCM of 2 and 20 is 20.

step 4 Write the fractions 17/2 and 7/20 in the addition expression form and multiply LCM with all the numerators and denominators of both fractions.
= 17/2 + 7/20
= [(17 x 20)/(2 x 20)] + [(7 x 20)/(20 x 20)]

step 5 Simplify the expression to have common denominator:
= 170/20 + 7/20

step 6 Take the common values out and rewrite the above expression like the below:
= 1/20 x (170/1 + 7/1)
= 1/20 x (170 + 7)

step 7Simplify the above expression further:
= 1/20 x 177
= 177/20
17/2 + 7/20 = 177/20
