Katerina incorrectly says the ratio y/x is 1/10. Which error did Katerina likely make?

She divided 30 by 1/10, Then rather than putting 300 down as the answer She put 1/10.

Step-by-step explanation: if you divide 30 by 1/10 you get 300, She may have put 1/10 because you need to put fractions in the blank squares.
