Question

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

• 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 $2\times (4\times m)$

$\mathrm{Given,\; 8}\times \left(2m\right)÷2=8m$

$\mathrm{a.\; 2}\times (4\times m)$
= 2 × (4m )
= 8m [True]

$\mathrm{b.\; 3}\times (5\times m-2\times m)$
= 3 × (3 m)
= 9m ≠ 8m [False]

$c.\; (3\times m+2\times m)$
= 3m + 2m
= 5m ≠ 8m [False]
