Question

what numbers give me a ratio of 3:4

Answer 1

A ratio 3:4 means:

$\frac{x}{y}=\frac{3}{4}$

Substituting with the values of the first table, we get:

$\begin{gathered} \frac{x_1}{y_1}=\frac{6}{8}=\frac{3}{4} \\ \frac{x_2_{}}{y_2}=\frac{7.5}{10}=\frac{3}{4} \\ \frac{x_3}{y_3}=\frac{9}{12}=\frac{3}{4} \end{gathered}$

Then, the ratio between x and y in table A is 3:4
