For example, if you are paid $12.50 for each hour you work, you could write that your hourly (unit) pay rate is $12.50/hour (read $12.50 per hour.)

How do you solve for unit rate?
How to Find Unit Rate? In a unit rate, the denominator is always 1. So, to find unit rate, divide the denominator with the numerator in a way that the denominator becomes 1. For example, if 50km is covered in 5.5 hours, the unit rate will be 50km/5.5 hours = 9.09 km/hour.
How do you solve for simple interest rate?
Simple Interest Formulas and Calculations:
- Calculate Interest, solve for I. I = Prt.
- Calculate Principal Amount, solve for P. P = I / rt.
- Calculate rate of interest in decimal, solve for r. r = I / Pt.
- Calculate rate of interest in percent. R = r * 100.
- Calculate time, solve for t. t = I / Pr.
How do you calculate interest rate example?
Simple Interest Formula
- (P x r x t) ÷ (100 x 12)
- Example 1: If you invest Rs.50,000 in a fixed deposit account for a period of 1 year at an interest rate of 8%, then the simple interest earned will be:

What is rate Summary?
A method of analysis is described whereby a model is first fitted to data in order to investigate assumptions, and subsequently the smoothed rates based on the model are summarized using an adjusted rate. We prefer directly adjusted rates when such a summarization is appropriate and the required data are available.
What is rate in simple interest?
