To find the decimal form of each fraction, we can divide them.
1 / 11 = 0.09090...
1 / 6 = 0.16666...
1 / 12 = 0.08333...
They are all repeating decimals. When you have a number that repeats itself ina decimal, you draw a line above that number. That means the number(s) keep repeating and never ends.
