A fraction from Latin fractus, "broken" represents a part of a whole or, more generally, any number of equal parts.

When students find their family, they are to write down their names and their family name. Students will be able to identify halves, thirds, and fourths. Introduction 5 minutes Tell students that today they are going to learn about fractions. Fractions look a little like division expressions, but they aren't problems to be solved.

The number 1 can be represented as a fraction because any number divided by itself is equal to 1 remember that the fraction notation means the same thing as division.

Mixed numbers can also be converted back into improper fractions. Cancel all common factors This procedure is just the opposite of building up a fraction by multiplying it by a fraction equivalent to 1. I started around the room having students tell me fractions, and I recorded their suggestions on the board.

Representing your ideas algebraically as I did on the chart is a handy way to refer to many, many fractions. Sometimes there is one more step. Now if you multiply a number by 1 it does not change its value, so if we multiply a fraction by another fraction that is equal to 1, we will not be changing the value of the original fraction.

That's because you have every part of the fraction, or one whole thing. What if we divided the same pizza into 12 slices instead of 8.

Particularities in writing and language[ edit ] Postal stamp, Ireland, After several steps you get the expression shown in blue. Tell students that families will consist of the following family members: If the whole number is even, divide it in half and multiply the denominator of the fraction by 2.

What if you take 2 slices. After some practice, draw a circle on the board. The lesson engages the students with algebraic thinking as the methods they suggest are translated to generalizations using variables to represent numerators and denominators.

Ask for one student as a volunteer. The procedure is illustrated in this example: The top number changed, since we're talking about 2 slices now. They must also write it in number form. Algebra Coach Exercises Improper fractions, mixed fractions and long division A fraction where the numerator is smaller than the denominator is called a proper fraction and a fraction where the numerator is bigger than the denominator is called an improper fraction.

This fraction equals 0. It's less than 1 whole thing, but more than 0. Jump to navigation Jump to search A cake with one quarter one fourth removed. If the numerator of a fraction is a multiple of the denominator then the fraction is equal to a whole number.

Fractions that have the same denominator are called like fractions. He nodded and raised a hand. Writing fractions Every fraction has two parts: Review and closing To close the lesson, review the definitions of fraction, numerator, and denominator.

You can also find the reciprocals of whole numbers. Remember, the whole number is always first. In the following example, Sally has been tasked with splitting available pies up equally among a group of five people.

A single serving is one-half of a pie. From working with the decimal portion of the fraction, Sally determined half of a pie (1/2) was available in addition to the two whole pies. If the top number and the bottom number of a fraction are the same, then the fraction is equal to 1.

That's because you have every part of the fraction, or one whole thing. This is sometimes known as a whole fraction. Fractions. Fractions, also called rational numbers, are numbers of the form, where a and b are integers (but b cannot be zero).

The bottom number is called the makomamoa.com of it as the denomination: it tells you what size units you are talking about—fourths, fifths, or whatever. To make a number a percent, you move the decimal to the right two times (placing a zero in any open/blank position).

To make a fraction, you read it out loud as 2 and four tenths. 2 #4/10# is simplified to 2 #1/5#. The way to write a decimal number as a fraction is to first separate out the whole number from the decimal part.

In our example, this gives us 2 as the whole number and as the decimal.

Next, convert the decimal part to a fraction. Writing out percentages correctly. I work in the legal field and it is necessary to write out percentages.

percent is latin for and what follows the point wd have to be a fraction or smaller number than or it wd make no sense. How would you write "four and a half percent" using only arabic numerals and symbols?

Answer: /2%.
