2. Cross multiplication method.

(10/3) + (4/15) using LCM Method:
What is 10/3 plus 4/15 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 10/3
Fraction B: 4/15

What to be found?
(10/3) + (4/15) = ?
Find what's the sum of 10/3 and 4/15.

step 2 Compare the denominators of fractions 10/3 and 4/15 to identify whether it is a like or unlike fraction addition. Since the denominators of given fractions 10/3 and 4/15 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 10/3 and 4/15:
The LCM of 3 and 15 is 15.

step 4 Write the fractions 10/3 and 4/15 in the addition expression form and multiply LCM with all the numerators and denominators of both fractions.
= 10/3 + 4/15
= [(10 x 15)/(3 x 15)] + [(4 x 15)/(15 x 15)]

step 5 Simplify the expression to have common denominator:
= 50/15 + 4/15

step 6 Take the common values out and rewrite the above expression like the below:
= 1/15 x (50/1 + 4/1)
= 1/15 x (50 + 4)

step 7Simplify the above expression further:
= 1/15 x 54
= 54/15
= 18/5
10/3 + 4/15 = 18/5

Hence,
10/3 plus 4/15 as a fraction is 18/5.
