Question

$901\times15, 89\times15, 10\times15$ if these numbers are multiplied and added then the result is equal to ______x15.

• A. 1000
• B. 100
• C. 500
• D. 1500

Answer 1

Answer:

A. 1000

To find the answer, you can use the distributive property of multiplication, which allows you to group the numbers being multiplied by 15.

The expression is:
$(901 \times 15) + (89 \times 15) + (10 \times 15)$

Since 15 is common to all terms, you can pull it out:
$(901 + 89 + 10) \times 15$

Now, add the numbers inside the bracket:
$901 + 89 + 10 = 1000$

So, the result is equal to 1000 x 15.
