2. Cross multiplication method.

(12/1) + (7/18) using LCM Method:
What is 12/1 plus 7/18 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 12/1
Fraction B: 7/18

What to be found?
(12/1) + (7/18) = ?
Find what's the sum of 12/1 and 7/18.

step 2 Compare the denominators of fractions 12/1 and 7/18 to identify whether it is a like or unlike fraction addition. Since the denominators of given fractions 12/1 and 7/18 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 12/1 and 7/18:
The LCM of 1 and 18 is 18.

step 4 Write the fractions 12/1 and 7/18 in the addition expression form and multiply LCM with all the numerators and denominators of both fractions.
= 12/1 + 7/18
= [(12 x 18)/(1 x 18)] + [(7 x 18)/(18 x 18)]

step 5 Simplify the expression to have common denominator:
= 216/18 + 7/18

step 6 Take the common values out and rewrite the above expression like the below:
= 1/18 x (216/1 + 7/1)
= 1/18 x (216 + 7)

step 7Simplify the above expression further:
= 1/18 x 223
= 223/18
12/1 + 7/18 = 223/18

Hence,
12/1 plus 7/18 as a fraction is 223/18.
