Question

Find the product of 15 and 100.

• A. 150
• B. 1500
• C. 15
• D. 15000

Answer 1

The correct option is B

1500

While multiplying large numbers that end with zero(s), we keep the zeros aside and perform the multiplication of the non-zero digits.

Then, we add the total number of zeros we kept aside at the end of the product.

Hence, to find $15\times 100,$ we find $15\times 1=15$ and add the two zeros in 1500 to the product 15.

i.e., $15\times 100=1500$
