How to solve dimensional analysis problems

You know that you need to take 4 doses per day (implied). Do you need to see her before leaving to get a refill? First, what do you want to know? You want to know how long the bottle will last. If you cant solve the problem, pick a different starting factor and start over. The dimensions of miles per hour has miles on top and hour on the bottom. This approach analyzes the dimensions of the problem and sets up a problem so that the starting dimension is changed to the answer by using a conversion fraction.

Our answer would still be the same how many feet per second are we traveling if we are going 60 miles per hour? Hour is 60 miles over 1 hour. In the below spreadsheet, i put in an input text field for the miles per hour. Using this method, you can hardly go wrong unless you push the wrong button on your calculator. By the way, how many pizzas should you order? Figuring this out should be as easy as. By the way, its possible to turn off the grid lines to make the setup look more like a standard equation to get the spreadsheet to calculate your answer, you would go to g1 and type an equal sign.

Dimensional analysis is a process to solve unit conversion problems. You figured out how much of the bottle you would use in one day. You could pick either of the following two factors as your starting factor now the trick is to pick from the other things you know another factor that will cancel out the unit you dont want. We want to find out how many feet are in 24 inches. ). Plug in conversion factors that cancel out the units you dont want until you end up with the units you do want. Again, units cancel if one is in numerator and one is in denominator. First we have to know that 12 inches equal one foot. A unit could be miles, gallons, miles per second, peas per pod, or pizza slices per person. Dimensional analysis (also known as the factor-label method or unit-factor method) is by far the most useful math trick youll ever learn.
