2. Cross multiplication method.

(5/2) + (9/20) using LCM Method:
What is 5/2 plus 9/20 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 5/2
Fraction B: 9/20

What to be found?
(5/2) + (9/20) = ?
Find what's the sum of 5/2 and 9/20.

step 2 Compare the denominators of fractions 5/2 and 9/20 to identify whether it is a like or unlike fraction addition. Since the denominators of given fractions 5/2 and 9/20 are not equal, it is said to be unlike fractions addition.

The LCM of 2 and 20 is 20.

step 4 Write the fractions 5/2 and 9/20 in the addition expression form and multiply LCM with all the numerators and denominators of both fractions.
= 5/2 + 9/20
= [(5 x 20)/(2 x 20)] + [(9 x 20)/(20 x 20)]

step 5 Simplify the expression to have common denominator:
= 50/20 + 9/20

step 6 Take the common values out and rewrite the above expression like the below:
= 1/20 x (50/1 + 9/1)
= 1/20 x (50 + 9)

step 7Simplify the above expression further:
= 1/20 x 59
= 59/20
5/2 + 9/20 = 59/20

Hence,
5/2 plus 9/20 as a fraction is 59/20.
