Question

Operations that satisfy closure property for whole numbers are:

• A. addition and multiplication
• B. addition and subtraction
• C. subtraction and division
• D. division and multiplication

Answer 1

The correct option is A addition and multiplication

For whole numbers, closure property is valid for addition and multiplication operations.
For example:
3 + 4 = 7 which is a whole number.
3 - 4 = -1 and which is not a whole number.
3 x 4 = 12 which is a whole number.
$\frac{3}{4}$ = 0.75 which is not a whole number.
