Question

Compare, in the box below, 0.5 and 0.5 when written as fractions. Make an observation about these repeating decimals when they are written as fractions. What do you notice that is similar about the original decimals and the numbers in the fractions they become? Where do the numbers from the decimals end up in their fractions?

Answer 1

0.5 repeating as a fraction is 5/9
0.5 as a fraction is 1/2

its 5/9 because it is closer to the next number since it is repeating.

the numbers in the decimals either end up as the numerator or the denominator
