Inflation of prices. Population growth, particularly in comparison between different countries. Decline of animal and bird populations. That's three for a start. Anything that has a change expressed as a fraction (over a day, month, year etc).
A fraction is a numerical constant. Being a fraction does not alter that. And, as a constant, its rate of change is precisely zero.
a car braking is a negative rate of velocity change
You divide it by 4.5 and then put it as a fraction
Rate of change of distance is called speed.Rate is defined as change with respect to time.
To change % to fraction: Divide the % by 100% Example: To change 93% to fraction: 93%/100% = 93/100
To find the rate of change. Velocity, for example, is the rate of change of distance - in a specified direction. Acceleration is the rate of change of velocity.
The population of a species over a period of time will change according to some rate of change.
The number you read on the speedometer of your car is the present rate of change of the distance you've covered.
a car going from stoplight to next intersection accelerates at a positive rate of velocity change
A trick for changing a decimal to a fraction is to say it aloud and write it out as how it says like for example .4 = 4/10 and you can simplify it. That would be a way you can change a decimal to a fraction.
4.25 isn't a whole number. You can change any whole number into a fraction by putting it over 1.
For example: 4/1 = 4.0
