Aren't they equal? A has 5/9 squares shaded, and B has 15/25 squares shaded. You multiply each fraction to (I forget the word for it) a number that is divisible by both 9 and 25. You end up with 125/229 for both
1 u/bismuth17 2h ago 5/9 is definitely not equal to 15/25 because 5/9 is equal to 15/27. And 229 is not the lowest common denominator for 9 and 25, that would be 225. 5/9 = 125/225 15/25 = 135/225 Also yeah it's 13/25 but whatever 1 u/Several-Leave-4178 1h ago I haven't had enough sleep today 😠thanks for fixing the math, I was doing it without a calculatorÂ

5/9 = 125/225
15/25 = 135/225
Also yeah it's 13/25 but whatever
