Question

Fill in the blank: $7\times (3\times (-1\left)\right)=(....\times .....)\times -1$

• A. $7,3$
• B. $7,-3$
• C. $-7,3$
• D. $-1,7$

Answer 1

The correct option is A $7,3$

Multiplication is associative for integers.
$i.e.a\times (b\times c)=(a\times b)\times c$
$\therefore 7\times (3\times (-1\left)\right)=(7\times 3)\times -1$
$\therefore$ The missing terms are $7,3.$
