Answer 1

Step-by-step explanation:

You think that zero is the decimal point here.

In the first question two zeros are there so we move the decimal point forward two places

2.75=275.

Here you can see that the decimal point is move forward two times now it is situated after 275 like this275.0 now here 275 is the whole number.

So, when we multiply 100 to the 2.75 the decimal point move forward two times.

Basic concept:-

• 2.75 X 10=27.5 (Here number of zero is one time so the decimal point move forward one time).
• 2.75 X 100=275 (Here number of zero is two time so the decimal point move forward two time).
• 2.75 X 1000=2750 (Here in this situation number of zero is three times but we can move the decimal point two times because there is no number, So we put a zero then we can move the decimal point three times forward).
• 2.75 X 10000=27500 (Here the number of zero is four times but we can move the decimal point two times forward,So we put two zeros because we can move forward the decimal two times but we have to move it four times forward so we put two zeroes in our answer and then we get the answer.
