Question

Select the expression that gives the same result as given by
$8\times \left(2m\right)÷2$

• A. $2\times (4\times m)$
• B. $3\times (5\times m-2\times m)$
• C. $3\times m+2\times m$

Answer 1

The correct option is A $2\times (4\times m)$

$8\times \left(2m\right)÷2=8m$
$2\times (4\times m)=2\times \left(4m\right)=8m\left(True\right)$$3\times (5\times m-2\times m)=3\times \left(3m\right)=9m\ne 8m\left(False\right)$

$(3\times m+2\times m)=3m+2m=5m\ne 8m\left(False\right)$
