Respuesta :

6 is 2/3 of 9, therefore, r is equal to 2/3 of 8 which is 5.333…

Answer:

Step-by-step explanation:

Cross multiply...some people learned this as "butterfly multiplication"

8/9 = r/6

Multiply top left times bottom right. And multiply bottom left times top right.

8*6 = 9r

48 = 9r

Divide both sides by 9

48/9 = r

This us a perfectly good answer. Or change it to a mixed number 5 1/3 or a decimal, rounded 5.3
