2. Cross multiplication method.

(13/2) + (9/10) using LCM Method:
What is 13/2 plus 9/10 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 13/2
Fraction B: 9/10

What to be found?
(13/2) + (9/10) = ?
Find what's the sum of 13/2 and 9/10.

step 2 Compare the denominators of fractions 13/2 and 9/10 to identify whether it is a like or unlike fraction addition. Since the denominators of given fractions 13/2 and 9/10 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 13/2 and 9/10:
The LCM of 2 and 10 is 10.

step 4 Write the fractions 13/2 and 9/10 in the addition expression form and multiply LCM with all the numerators and denominators of both fractions.
= 13/2 + 9/10
= [(13 x 10)/(2 x 10)] + [(9 x 10)/(10 x 10)]

step 5 Simplify the expression to have common denominator:
= 65/10 + 9/10

step 6 Take the common values out and rewrite the above expression like the below:
= 1/10 x (65/1 + 9/1)
= 1/10 x (65 + 9)

step 7Simplify the above expression further:
= 1/10 x 74
= 74/10
= 37/5
13/2 + 9/10 = 37/5

Hence,
13/2 plus 9/10 as a fraction is 37/5.
