5/8 x w = 9
So basically 5/8 x what equals 9

(5/8)(w) = 9
w = 9 / (5/8)
w = (9)(8) / 5
w = 72/5
w = 14.4

I hope this helps!

The first one, i believe, would be correct. all the others have one thing in common, and that's that they have repeating numbers. in the second one, x and y have repeating 6's and 3's, and in the third, x and y have repeating 6's as well. in the last one, there are repeating 3's. the first one has no repeating numbers.
