Question

To represent the products of decimal number such as 0.7*0.3

Answer 1

Answer:

0.21

Step-by-step explanation:

First, multiply the numbers without the decimal point:

7*3 = 21

As you can see, there is one digit after the decimal point in 0.3 and the same is for 0.7. If we add the number of digits after the decimal point of both the numbers, i.e. 1+1, we get 2.

Now, move from right to left in the number 21 and put a decimal point after 2 digits. So you will get .21. The last step is to add a 0 before it and you will get 0.21 which is the final answer!

Hope this helps :-)
