In the table below, write each power of

Describe how the decimals and fractions change as you progress down the table.

Do you notice any patterns? Try to fill in the rest of the table on your own.

Notice that the decimal point moves to the left one spot as the value of the exponent decreases, while the denominator in the fraction form increases by a multiple of

. How would you tell someone how to write

as a fraction? You do not have to write the actual fraction. From the table, you see that the magnitude of the exponent corresponds to the number of zeros in the denominator of the fraction form of the number.

Therefore the fraction form of this number would have

over a denominator of with zeros following.
