Step-by-step explanation:
5/33 = (5·3)/(33·3) = 15/99 = 0.151515151515...
_____
You may recall that 1/9 = 0.11111...(repeating indefinitely). That is, a multiple of 1/9 is a single-digit repeating decimal.
Likewise, 1/99 = 0.01010101...(repeating indefinitely). This means when a 2-digit numerator has 99 as the denominator, the decimal equivalent is that number repeated indefinitely. Any fraction with 999 as the denominator is a 3-digit repeat in decimal; 9999 as the denominator gives a 4-digit repeat, and so on.
This is how you do it. Set two equations equal to each other then solve. Plug in x for each equation, find the answers. AC is the base because it is not congruent to any other side.
