Rate per hour calculator how to#
Now that we have the unit rate definition out in the open, it's time to see how to find this unit rate.
We have prepared two tools for the two above topics, namely, the scale calculator and density calculator. The latter is a unit rate example, and, in fact, most of physics is. To convince yourself of that, recall how a map scale is always given in the form 1:30,000,000, which is a ratio, while we measure the density of objects in ounces or grams per cubic inch (or centimeter), which is a rate. After all, it might be useful to know that the 21 dog treats per week translate to three treats a day.Īs we've seen, ratios and rates are connected but it's quite impossible to say that one is better than the other. Or, if you prefer a more scientific unit rate definition, it is a way to translate the rate as we have it into the equivalent fraction with the denominator 1.
So, what is a unit rate? It is the same thing but with the second number equal to 1. Note how colloquially, we'd react to that with something like, " At this rate, I'll have to buy more in a couple of days." The word " rate" is no coincidence here. If, in a week, it eats twenty-one treats, then the corresponding rate is 21 treats per 7 days. Say that you have a dog and you give him treats every now and then. This vague definition is better explained with an example. The rate, on the other hand, tells you how much of the first number corresponds to how much of the second. If not, then perhaps it's best to spend some more time studying? If it's larger than 1 (i.e., the first number is larger than the second), then you're above the average. Then the ratio 75 / 62 describes your score in terms of the mean. For instance, say that you got 75% on the test, and the class average was 62%. We often present it as a fraction, although not always. Mathematically speaking, this comparison is called the ratio. Why didn't you?" And when you get an average grade, but it's one of the best ones in class, you hear, " You shouldn't look at other kids!" Funny how people can choose to compare two values only when it suits their purposes. You know how, when you get a good grade, your parents say, " But your friend Jack got a better one.
