(12/11) + (3/10) using LCM Method:
What is 12/11 plus 3/10 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 12/11
Fraction B: 3/10

What to be found?
(12/11) + (3/10) = ?
Find what's the sum of 12/11 and 3/10.

step 2 Compare the denominators of fractions 12/11 and 3/10 to identify whether it is a like or unlike fraction addition. Since the denominators of given fractions 12/11 and 3/10 are not equal, it is said to be unlike fractions addition.

step 4 Write the fractions 12/11 and 3/10 in the addition expression form and multiply LCM with all the numerators and denominators of both fractions.
= 12/11 + 3/10
= [(12 x 110)/(11 x 110)] + [(3 x 110)/(10 x 110)]

step 5 Simplify the expression to have common denominator:
= 120/110 + 33/110

step 6 Take the common values out and rewrite the above expression like the below:
= 1/110 x (120/1 + 33/1)
= 1/110 x (120 + 33)

step 7Simplify the above expression further:
= 1/110 x 153
= 153/110
12/11 + 3/10 = 153/110
