Get out your paper & pencil because I have a new puzzle for you!!

PUZZLE #10 Fractions can be fun! Nov. 13 -Nov. 17

Changing fractions to decimals can be fun. The fractions which

use 9 as the denominator are one of my favorites.

Remember when you change a fraction to a decimal there

is a pattern to the decimal form??

For example 1/2 = 0.500. . . and 1/3 = 0.33333. . .

Compute the decimal form of the fractions 1/9, 2/9, . . . , 8/9.

Do you see a pattern in the decimal form for each fraction?

What is it?

Add the decimal forms for 1/9 and 2/9 by hand and show that you

get the decimal form for 3/9 (which is 1/3).

Do the same for 1/9 and 8/9. (be sure to do this calculation

by hand since calculators will automatically change this answer to

something else!)

Explain what happens in this last case.
