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
