Question

Match the following.

• A. 10500
• B. 6600
• C. 15400
• D. 54000

Answer 1

Firstly, take out the zeros from both the numbers. Now, mutiply both the numbers and finally add all the zeroes to the end of the product.

For example, before finding the product of 150 and 70, we find the product of 15 and 7.

$15\times 7=105$

Now, adding the two zeroes into the product, we have

$150\times 70=10500.$

Similarly,

$20\times 330=6600,$

$770\times 20=15400$ and

$540\times 100=54000.$
