Step-by-step explanation:

We are given that a whole number is added to a number with two digits after the decimal point.

We have to find the number of digits in sum  after the decimal point.

Suppose  a whole number 12 and a decimal number with two digits after decimal point is 4.56.

Sum=12+3.56

Sum=15.56

Hence, the sum have two digits after the decimal point.
