2. Cross multiplication method.

(17/4) + (3/20) using LCM Method:
What is 17/4 plus 3/20 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 17/4
Fraction B: 3/20

What to be found?
(17/4) + (3/20) = ?
Find what's the sum of 17/4 and 3/20.

step 2 Compare the denominators of fractions 17/4 and 3/20 to identify whether it is a like or unlike fraction addition. Since the denominators of given fractions 17/4 and 3/20 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 17/4 and 3/20:
The LCM of 4 and 20 is 20.

step 4 Write the fractions 17/4 and 3/20 in the addition expression form and multiply LCM with all the numerators and denominators of both fractions.
= 17/4 + 3/20
= [(17 x 20)/(4 x 20)] + [(3 x 20)/(20 x 20)]

step 5 Simplify the expression to have common denominator:
= 85/20 + 3/20

step 6 Take the common values out and rewrite the above expression like the below:
= 1/20 x (85/1 + 3/1)
= 1/20 x (85 + 3)

step 7Simplify the above expression further:
= 1/20 x 88
= 88/20
= 22/5
17/4 + 3/20 = 22/5

Hence,
17/4 plus 3/20 as a fraction is 22/5.
