Question

Find the product $128\times 24$ using distributive property.

• A. $3,062$
• B. $2,972$
• C. $3,052$
• D. $3,072$

Answer 1

The correct option is D $3,072$

To find: $128\times 24$ using distributive property.

$128\times 24=128\times (20+4)$
Now, applying distributive property
$128\times (20+4)=128\times 20+128\times 4$
$=128\times 2\times 10+128\times 4$
Now, finding products $128\times 2$ and $128\times 4$ as in below figures,



$=128\times 2\times 10+128\times 4$
$=256\times 10+512$
$=2,560+512$
$=3,072$

$\therefore$ $128\times 24=3,072$.
(d) is the correct option
