Answer 1

Answer:

In these sorts of questions, we need to check the number of decimal points, namely- the number of digits from the right after which the decimal point has been placed.

In case of 125.7 that is 1 and in the case of 0.05 it is 2.

Therefore let us keep that in mind and multiply the numbers without any decimal points. That product is given to us as 6285.

Now in the product, we skip three digits from the right and place the decimal point to get the product of 125.7 and 0.05.

This will be 6.285.
