Chapter 8, Problem 5RP

To determine

To find the ratio of “ x ” to “ y ”.

Answer to Problem 5RP

The ratio of “ x ” and “ y ” is equal to $\frac{4}{9}$ .

Explanation of Solution

Given information:

  $9x=4y$

Formula used:

The Means Extremes product theorem is used:

In a proportion, the product of the means is equal to the product of the extremes.

This theorem allow us multiply out a proportion.

If $\frac{a}{b}=\frac{c}{d}$ , then $ad=bc.$

Calculation:

  $9x=4y$

  $\therefore \frac{x}{y}=\frac{4}{9}$
