What Does per Mean in Math?

Per is a mathematical term that is typically used in relation to division. When something is divided into a certain number of parts, the parts are called "per" (e.g. "divided into four parts would be four per"). In some cases, the term can be used more generally to mean "for each" (e.g. "there are four students per class").

Per is often used in math as a way to abbreviate the word "percent." It is a way of denoting a particular portion or share out of a total. For example, when we say that a certain number is "5%," we are saying that it is 5 per 100, or 5 parts out of 100. Similarly, when we see the symbol "%" next to a number, we know that it stands for "per 100" or "out of 100."

But per can also be used more generally to mean "for each." For example, we might say that there are 100 students in a classroom, and "10 of them are girls." In this case, we would be saying that there are 10 girls per 100 students in the classroom.

When we multiply or divide by a certain number of "pers," we are effectively changing the scale that we are working on. For example, if we divide aLength by 2 pers, we are effectively halving the length.

If we are looking at a graph, and we see that the line goes up by 5% per year, this means that for each year that passes, the line goes up by 5%. We can similarly talk about percentages of other things - such as how much a population grows or declines per year.

In conclusion, per is a very versatile little word that can be used in a variety of ways in math. Whether we are talking about shares, proportions, or simply scaling something up or down, per is often the word that we need.

Per is short for percentage. Addition is the process of putting two or more numbers together to get a total. The relationship between per and addition is that percentage is a way of indicating part of a whole, and addition is the process of putting numbers together to get a total. In other words, addition is the process of finding out how many there are in total, and percentage is a way of indicating what part of that total a certain number is.

Per is short for percent. Percent means per hundred. So, 45% is 45 per 100, or 45 out of 100.

To find a percent of a number, we divide the number by 100 and then multiply by the percent. For example, to find 45% of 500, we would divide 500 by 100 to get 5, then multiply 5 by 45 to get 225.

To find what percent one number is of another, we divide the first number by the second number, then multiply by 100. For example, 500 is 100% of 500, because 500 divided by 500 is 1, and 1 multiplied by 100 is 100. To find what percent 45 is of 500, we divide 45 by 500 to get 0.09, then multiply by 100 to get 9%.

9% is the answer to the question, "What is the relationship between 45 and 500?"
