Explain how the value of the ratio can be seen in the table.
Explain how the value of the ratio can be seen in the equation R =5W.
The values in the first column show the values in the ratio. The ratio of the minutes running to the minutes walking is 5:1 . The value of the ratio is 5
1
The minutes running is represented as R . The minutes walking is represented as W in the equation. The value is represented because the amount of running is five times as much as the amount of walking or R = 5W.
