Solution:
The shortcut for dividing decimal numbers by numbers such as 10, 100, and 1000:
<em>Move the decimal point to the left as many places as there are zeros in the factors 10, 100 and 1000.</em>
Product of 122.1 and
:
![$122.1\times\frac{1}{100} =\frac{122.1}{100}](https://tex.z-dn.net/?f=%24122.1%5Ctimes%5Cfrac%7B1%7D%7B100%7D%20%3D%5Cfrac%7B122.1%7D%7B100%7D)
= 1.221 (There are 2 zeroes, so move 2 places left)
Product of 122.1 and
= 1.221
Product of 11.8 and
:
![$11.8\times\frac{1}{100} =\frac{11.8}{100}](https://tex.z-dn.net/?f=%2411.8%5Ctimes%5Cfrac%7B1%7D%7B100%7D%20%3D%5Cfrac%7B11.8%7D%7B100%7D)
= 0.118 (There are 2 zeroes, so move 2 places left)
Product of 11.8 and
= 0.118
Product of 1350.1 and
