2. Cross multiplication method.

(2/4) + (1/78) using LCM Method:
What is 2/4 plus 1/78 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 2/4
Fraction B: 1/78

What to be found?
(2/4) + (1/78) = ?
Find what's the sum of 2/4 and 1/78.

step 2 Compare the denominators of fractions 2/4 and 1/78 to identify whether it is a like or unlike fraction addition. Since the denominators of given fractions 2/4 and 1/78 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 2/4 and 1/78:
The LCM of 4 and 78 is 156.

step 4 Write the fractions 2/4 and 1/78 in the addition expression form and multiply LCM with all the numerators and denominators of both fractions.
= 2/4 + 1/78
= [(2 x 156)/(4 x 156)] + [(1 x 156)/(78 x 156)]

step 5 Simplify the expression to have common denominator:
= 78/156 + 2/156

step 6 Take the common values out and rewrite the above expression like the below:
= 1/156 x (78/1 + 2/1)
= 1/156 x (78 + 2)

step 7Simplify the above expression further:
= 1/156 x 80
= 80/156
= 20/39
2/4 + 1/78 = 20/39

Hence,
2/4 plus 1/78 as a fraction is 20/39.
