K-12 For Students

One of the keys to solving problems in courses like physics and chemistry is getting the units right. A deep understanding of units, what they describe and how to manipulate them will drastically...

Rounding fractions is an important tool in everyday life. This includes cooking, hands-on job skills such as plumbing and engineering and as simple as telling time. Learning to round fractions...

Multiplying fractions is not that difficult, as long as you know your multiplication facts or you know how to figure out a multiplication problem. The difficult part is what to do with your answer...

In arithmetic, multiplying and diving fractions is relatively straightforward. To multiply fractions, simply multiply the numerators, then multiply the denominators. Reduce to lowest terms if...

In arithmetic, adding and subtracting fractions is a relatively straightforward process. Take 1/2 + 1/3. The easiest way to perform the operation is to multiply denominators 2 times 3 and use 6 as...

Fractions with the same value can be expressed in different ways. For example, 20/40 has the same value as ½. If you could master canceling fractions, you can make multiplying fractions...

A fraction is a type of numeral that establishes a relationship between a part of something and a whole object. They are used in cooking, chemistry, construction and any other discipline in which...

Fractions can be proper, improper or mixed. A fraction is proper if the numerator is less than the denominator (1/2, 3/4). A fraction is improper if the numerator is greater than the denominator...

Comparing fractions can be useful in your everyday life once you have finished elementary school. There are times when you might not quite remember how to do it. It really is not too difficult...

In mathematics, the term rational expression denotes a representation of the form p/q where both p and q are polynomials. There are many times when we will need to combine two or more rational...

Adding and subtracting radical expressions with fractions is exactly the same as adding and subtracting radical expressions without fractions, but with the addition of rationalizing the...

The term factorial is a mathematical expression that represents taking a non-negative integer and multiplying it by all positive integers less than the original number. For example, the factorial...

We all work with fractions everyday, and often we don't even realize it. Many of the operations become so ingrained in our minds that we can do them without thinking about them. Because of this,...

Fractions are simply proportions of a whole. There are two parts to a fraction, a numerator which is the top number, and a denominator which is the bottom number. In mathematics, for a fraction...

A fraction has a numerator on the top and a denominator on the bottom. The reciprocal of a fraction is obtained by switching the numerator with the denominator.

It's not uncommon to be stumped by changing a fraction to a decimal. When you break it down and take your time, it doesn't have to be difficult at all! Follow these easy steps, and you will never...

A fraction is a part of a whole (such as 1/2 or 4/5). It is written with a number on the top and a number on the bottom. The top number is called a numerator and the bottom number is called a...

Zero is one of the rock stars of mathematics. Although it was only invented as a concept in the fourth or fifth century B.C., it confounded even philosophers. They asked, "How can nothing be...

A mixed fraction is a whole number combined with a fraction. For example, 2 3/4 is a mixed fraction. The number 2 is the whole number, the number 3 is the numerator (upper fraction), and the...
