2. Cross multiplication method.

(18/7) + (5/2) using LCM Method:
What is 18/7 plus 5/2 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 18/7
Fraction B: 5/2

What to be found?
(18/7) + (5/2) = ?
Find what's the sum of 18/7 and 5/2.

step 2 Compare the denominators of fractions 18/7 and 5/2 to identify whether it is a like or unlike fraction addition. Since the denominators of given fractions 18/7 and 5/2 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 18/7 and 5/2:
The LCM of 7 and 2 is 14.

step 4 Write the fractions 18/7 and 5/2 in the addition expression form and multiply LCM with all the numerators and denominators of both fractions.
= 18/7 + 5/2
= [(18 x 14)/(7 x 14)] + [(5 x 14)/(2 x 14)]

step 5 Simplify the expression to have common denominator:
= 36/14 + 35/14

step 6 Take the common values out and rewrite the above expression like the below:
= 1/14 x (36/1 + 35/1)
= 1/14 x (36 + 35)

step 7Simplify the above expression further:
= 1/14 x 71
= 71/14
18/7 + 5/2 = 71/14

Hence,
18/7 plus 5/2 as a fraction is 71/14.
