Answer 1

When a whole number is added to a number with two digits after the decimal point, the sum will have two digits after the decimal point.

Step-by-step explanation:

When a whole number is added to a number with two digits after the decimal point, the sum will have two digits after the decimal point. This is because when you add a whole number to a decimal, the decimal part of the sum remains unchanged. For example, if you add 5 to 3.45, the sum is 8.45.
