Which number is denominator

The denominator shows the total amount of parts that make up a whole. Fractions represent a part of a whole or, more generally, any number of equal parts. Mathematically, it is shown by the division of two numbers.

Here, 1 is the numerator and 4 is the denominator. The denominator indicates how many of those parts make up a unit or a whole. The numerator indicates the number of parts that we have selected out of the total number of equal parts. Look at the fraction model below. Three portions are shaded Numerator out of the total 5 portions created denominator. Some examples of denominators are given in the table below:. When the denominators of two or more fractions are the same, they are known as the common denominators.

The least common denominator LCD is the smallest number that can be a common denominator for a given set of fractions. Addition and subtraction of fractions and comparing two or more fractions are possible only if the fractions have common denominators.

Since the denominators are the same, they are like fractions and can be instantly added up. Like fractions are the fractions that have the same denominators. Unlike fractions are the fractions which have different denominators. Let us see some examples here to add and subtract fractions with common denominators.

If you have different denominators, we have two methods to find the sum or difference of two or more fractional numbers:. Example 1: Rita ordered a pizza at a restaurant. The line can be horizontal or slanted—they both mean the same thing and simply serve to separate the numerator from the denominator.

But denominators are a bit trickier. What is a denominator? First, the bottom part—the denominator. What does the denominator tell you? The denominator of a fraction tells you how many parts a whole is broken into.

It can be a whole pineapple, a whole song, or a whole anything. If the denominator of a fraction is, say, 4, then that indicates that the whole whatever is broken up into 4 equally-sized pieces.

Or, if the denominator is 12, that means the whole whatever is broken-up into 12 equally-sized pieces. Well, that leads us to the meaning of the numerator. What is a numerator and what does it tell you? How, then, do we put this all together to understand the meaning of fractions?

In all the examples so far, the numerator has always been smaller than the denominator. But what would it mean if the numerator were bigger than the denominator? The denominator, 4, indicates that a whole is divided into four equally sized parts, and the numerator, 7, indicates that we have seven of those parts.

So, if four parts make a whole, and we have seven, then we must have a whole object plus three more of the equally sized parts. Fractions: denominators and numerators. Fractions equivalency wall.
