If you’re looking for an easy way to learn about decomposing fractions based math, you should check out the next article in this series: 4th Grade Math Solutions Using Decomposing Fractions! In that article, we’ll review the basic concepts of decomposing fractions, as well as look at how they relate to other areas of fifth grade math.
A fraction is a number whose denominator is a number. For example, 6/3 means “three times six”, or “three-quarters of three.” Many common fractions can be used with other numbers. For example, six/five equals “three and five,” which is a fraction with one unit (or fraction), and ten/six equals “four and six” which is a fraction with two units (or fractions).
When working with a fraction, you need to be aware of the different denominators. If you are working with a number such as “half a dollar”, you’ll have two denominators. But if you were working with a number like “a quarter,” you’ll have three denominators.
When working with a fraction, the easiest way to describe it is as a unit of measure with one unit (or fraction) of change. You can think of a fraction as being a measure of change over time. This is how most math teachers explain the idea behind dividing up a problem into smaller parts. We are only allowed to do so much with a problem, though, because the larger parts are often harder to understand. So you might be looking at “the price of a ticket” in tenths of a penny.
When dealing with a fraction, remember that the larger parts often represent a change in value, or a change in proportion. In order to describe a fraction in terms of its units, the change in the units is usually called the numerator. The denominator represents the change in units, and is called the denominator. Here are a few common denominators for a fraction, based on the above definition:
You can look at the table above to get a better idea of the meaning of the numerator and denominator. Remember that both numerator and denominator must be included in a calculation if you want to get the correct answer.
Decomposing fraction is a bit different from standard division. The difference is that dividing a whole number by a denominator usually results in a fraction that can be used with other numbers. Decomposing a fraction is not as straightforward as dividing by the denominator, because it involves some additional steps.
A good rule of thumb is to break down a fraction to its components and work your way from left to right. Once you’ve worked your way through each section of the fraction, you’ll be able to divide the whole number into its component parts.
