7. In an orchestra, the ratio of trombones to violas is 4:6. There are 9 violas. Write and solve a proportion to
determine how many trombones are in the orchestra.

Respuesta :

Answer: 6 trombones

Step-by-step explanation:

We can set up a proportion.

Let x be the number of trombones there are.

[tex]\frac{4 trombones}{6violas} = \frac{x trombones}{9 violas}[/tex]

We can cross multiply:

4*9 = 6x

6x = 36

Divide both sides by 6:

x = 6
