2. Cross multiplication method.

(2/5) + (1/45) using LCM Method:
What is 2/5 plus 1/45 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 2/5
Fraction B: 1/45

What to be found?
(2/5) + (1/45) = ?
Find what's the sum of 2/5 and 1/45.

step 2 Compare the denominators of fractions 2/5 and 1/45 to identify whether it is a like or unlike fraction addition. Since the denominators of given fractions 2/5 and 1/45 are not equal, it is said to be unlike fractions addition.

The LCM of 5 and 45 is 45.

step 4 Write the fractions 2/5 and 1/45 in the addition expression form and multiply LCM with all the numerators and denominators of both fractions.
= 2/5 + 1/45
= [(2 x 45)/(5 x 45)] + [(1 x 45)/(45 x 45)]

step 5 Simplify the expression to have common denominator:
= 18/45 + 1/45

step 6 Take the common values out and rewrite the above expression like the below:
= 1/45 x (18/1 + 1/1)
= 1/45 x (18 + 1)

step 7Simplify the above expression further:
= 1/45 x 19
= 19/45
2/5 + 1/45 = 19/45

Hence,
2/5 plus 1/45 as a fraction is 19/45.
