Question

The table shows a proportional relationship between x and y. Katerina has to complete the table. Katerina incorrectly says the ratio у 1 x is 10. Complete the table. What error did Katerina likely make? X 3 5 7 у y Ratio Х 30 ? 50 ? 70 ?

Answer 1

Since the ratio is given by:

`(y)/(x)`

The error that Katerina made awas that she did x/y, then to complete the table:

`\begin{gathered} (30)/(3)=10 \\ (50)/(5)=10 \\ (70)/(7)=10 \end{gathered}`
