Fractions to Decimals Use a Calculator to change each of these fractions to a decimal. Write all the digits that appear in the calculator’s display. 1 1 3 4 3 5 5 6 5 11 8 12 3 3 10 11 How are the decimals in the first column different from those in the second column? Define Rational Numbers: All rational numbers can be written as decimals that either terminate (end), like those in the first column, or repeat forever in a pattern, like those in the second column. Show that each number is a rational number by writing it as a ratio of integers. 0.7 -‐6 4 15% − 11 -‐4.3 115%
Repeating Decimals To indicate that a decimal repeats forever in a specific pattern, you write a bar over the repeating digits. ! For example, !! = 0.54545454545 … You can write this decimal as 0. 54. The use of a line to show the repeating digits in a decimal is called bar notation. Write each of these fractions in decimal form using bar notation, if necessary. 1 2 3 3 11 3 12 11
