Answer:

8 38/45 inches

Step-by-step explanation:

A regular size chocolate bar is 5 and 4/9 inches long. If the king size bar is 3 and 2/5 inches longer, what is the length of the king size bar?

Let us represent:

Length of regular size chocolate bar = x

Length of king size chocolate bar = y

A regular size chocolate bar is 5 and 4/9 inches long.

x = 5 4/9 inches

If the king size bar is 3 and 2/5 inches longer,

Hence:

y = x + 3 2/5 inches

The length of the king size bar is calculated as:

5 4/9 inches + 3 2/5 inches

(5 + 3) + ( 4/9 + 2/5)

Lowest common denominator = 45

8 + (20 + 18/45)

8 38/45 inches
