The denominator is the bottom number of a fraction and represents the whole in its entirety.

For example:

The denominator is the bottom number of a fraction and represents the whole in its entirety.

For example:

Write the fraction shown in the drawing, in numbers:

In this article, you will learn everything you need to know about the denominator and its function in fractions.

The denominator is one of the components of a fraction, therefore, to better understand what the denominator is, let's first talk about fractions.

A fraction is a number that is composed of two numbers:

The upper one which is called the numerator

A fractional line that represents a division

And the lower number which we call the denominator

**For example:**

The fraction could represent a certain part or even the entirety of a whole.

Question 3

What is the marked part?

The denominator represents the whole itself, that is, the totality of parts or portions there are.

For example, in the fraction

$7 \over 8$,

The denominator indicates that $8$ is the whole, in total there are $8$ parts.**Explanatory note as a gift**: The $7$ in the numerator represents a certain part within the whole $7$ parts within $8$, that is, $7$ eighths.

**Let's see it illustrated:**

**Discover the fractions whose denominator is** **$2$****:**

$\frac{2}{3}, \frac{5}{2}, \frac{2}{2}, \frac{7}{7}$

**Solution:**

$\frac{5}{2}$

In this fraction, the denominator is **$2$** –> the number located at the bottom.

$\frac{2}{2}$

In this fraction, the denominator is **$2$** –> the number located at the bottom.

What is the marked part?

Write $3$ fractions whose denominator is $5$:

**Solution:**

$\frac{2}{5}, \frac{12}{5}, \frac{5}{5}$

In the three fractions we wrote, the denominator is $5$. Any fraction you write that has the number $5$ as the denominator and any whole number as the numerator will be a correct answer.

What is the marked part?

We can see that there are three shaded parts out of six parts in total,

that is - 3/6

But this is not the final answer yet!

Let'snotice that this fraction can be reduced,

meaning, it is possible to divide both the numerator and the denominator by the same number,

so that the fraction does not lose its value. In this case, the number is 3.

3:3=1

6:3=2

And so we get 1/2, or one half.

And if we look at the original drawing, we can see that half of it is colored.

$\frac{1}{2}$

My numerator is 6 and my denominator is 7.

Which am I?

Remember that the numerator of the fraction is the top, while the denominator of the fraction is the bottom.

Now we'll place them accordingly and get:

$\frac{6}{7}$

$\frac{6}{7}$

What fraction results from dividing 8 by 16?

Write the exercise:

$8:16$

Now write it in the form of a simple fraction, remembering that the numerator is above and the denominator is below:

$\frac{8}{16}$

Divide the numerator and denominator by the number that divides both of them, in this case the number is 8:

$\frac{8:8}{16:8}=\frac{1}{2}$

$\frac{1}{2}$

My numerator is 4 and my denominator is 8.

Which am I?

Recall that the numerator is the top number, and the denominator is the bottom number.

Now let's represent it accordingly:

$\frac{4}{8}$

Let's divide the numerator and denominator by 4:

$\frac{4:4}{8:4}=\frac{1}{2}$

$\frac{1}{2}$

$18:3=$

Let's write the expression in the following form:

$\frac{18}{3}$

We'll divide both the numerator and denominator by 3 and get:

$\frac{6}{1}=6$

$6$
