This would be so easy for you to solve, in about 3 minutes with a calculator.
A fraction means division ... (the top number) divided by (the bottom number).
Take the fraction part of each choice, do the division for each one,
and see which one gives you 0.4545... repeating.
A). 227/500 = 0.454 That's not 0.45 repeating.
B). 9/20 = 0.45 That's not 0.45 repeating.
C). 5/11 = 0.4545... THAT's 0.4545... repeating !
D). 9/2 = 4.5 That's not 0.45 repeating.
9x - y = -7 is the answer
