❖ She threw the ball 10 yards.
The ratio we have is 3:1. Right now, we know she threw 30 feet. The relationship between the 3 and 30 is multiplying by 10. If you are multiplying the feet by 10, you have to multiply the yards by 10. When you multiply 1 x 10, you get 10. So the ration is 30:10 and she threw 10 yards.
