Question

......... are associative for rational numbers.

• A. Multiplication and addition
• B. Multiplication and subtraction
• C. Division and subtraction
• D. Division and addition

Answer 1

The correct option is A Multiplication and addition

Multiplication and addition are associative for rational numbers because when any three rational numbers are added or multiplied, the result so obtained will remain the same irrespective of the change in their order. i.e. $a+(b+c)=(a+b)+c$
$a\times (b\times c)=(a\times b)\times c$.
