To multiply a decimal by we shift the decimal point one space to the right.
To demonstrate, let's find the value of
First, we write down our number. We can attach as many trailing zeros as we want to the decimal part.
Now, we count the zeros in Since contains zero, we move the decimal point place to the right:
This gives the following diagram:
We ignore the leading zeros in the whole number part and trailing zeros in the decimal part. This gives the following number:
Therefore:
What is
First, we write down our number. We can attach as many trailing zeros as we want to the decimal part.
Now, we count the zeros in Since contains zero, we move the decimal point place to the right:
This gives the following diagram:
We ignore the leading zeros in the whole number part and trailing zeros in the decimal part. This gives the following number:
Therefore:

To multiply decimals by larger powers of ten, we shift the decimal point spaces to the right, where is the number of zeros in the power of ten.
To illustrate, let's compute the value of
First, we write down our number. We can attach as many trailing zeros as we want to the decimal part.
Now, we count the zeros in Since contains zeros, we move the decimal point places to the right:
This gives the following diagram:
We ignore the leading zeros in the whole number part and trailing zeros in the decimal part. This gives the following number:
Therefore:
Find the value of
First, we write down our number. We can attach as many trailing zeros as we want to the decimal part.
Now, we count the zeros in Since contains zeros, we move the decimal point places to the right:
This gives the following diagram:
We ignore the leading zeros in the whole number part and trailing zeros in the decimal part. This gives the following number:
Therefore:
