To determine the rate of a number do the following steps:


   Multiply the number by the percent (e.g. 87 * 68 = 5916)

   Divide the answer by 100 (Move decimal point two places to the left) (e.g. 5916/100 = 59.16)

   Round to the desired precision (e.g. 59.16 rounded to the nearest whole number = 59)

ROC is often used when speaking about momentum, and it can generally be expressed as a ratio between a change in one variable relative to a corresponding change in another; graphically, the rate of change is represented by the slope of a line.
