Question

Operations that do not satisfy closure property for whole numbers are:

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

Answer 1

The correct option is C subtraction and division

For whole numbers, closure property is valid for addition and multiplication operations.
Closure property is not valid for subtraction and division operations.
For example:
3 + 4 = 7, which is a whole number.
3 - 4 = -1, 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.
