## Converting a decimal fraction to a mixed number

The transition from a decimal fraction to a mixed number is simple and easy if you just know the right way.

To do it correctly without making mistakes, we recommend that you make sure you know how to read decimal fractions properly.

If you know how to read decimal fractions correctly – the path to success in transitioning from a decimal fraction to a simple fraction is completely paved for you.

### How do you read a decimal fraction?

A decimal fraction represents a fraction or a non-whole number using a decimal point.

The decimal point divides the fraction as follows:

*Notations in a Word file*

#### Explanation:

The entire part to the left of the decimal point is called whole numbers.

The entire part to the right of the decimal point is divided as follows:

The first digit after the point represents tenths

The second digit after the point represents hundredths

The third digit after the point represents thousandths

Remember! There is no unity – the counting starts from tenths.

**How do we know the denominator of the mixed fraction?**

As we saw above, decimal fractions consist of whole numbers that are before the decimal point and parts that are after the decimal point, where the parts are made up of tenths, hundredths, and thousandths.

If we convert the tenths, hundredths, and thousandths to a denominator in a simple fraction, we get:

**Remember:**

Thousandths – 1000 in the denominator

Hundredths – 100 in the denominator

Tenths – 10 in the denominator

How will you remember this?

It is very easy and simple.

Tenths come from the word 10, so the denominator that should appear is 10.

Hundredths come from the word 100, so the denominator that should appear is 100.

Thousandths come from the word 1000, so the denominator that should appear is 1000.

The key to success lies here:

To read a decimal fraction correctly, we need to ask ourselves what the last digit in the decimal fraction represents.

**For example:**

How do we read the decimal $9.56$?

6 is the last digit and it represents hundredths, so we read the decimal as $9$ whole and $56$ hundredths.

How wonderful! We just learned the notation for hundredths - *Notation in a Word file*

All that remains for us is to put $56$ in the numerator, $9$ in the whole number part and get the simple fraction of the decimal $9.56$:

$9 \frac{56}{100}$

**Let's practice more:**

Convert the decimal $4.2$ to a mixed number

Solution:

Let's ask ourselves – how do we read the fraction?

$4$ wholes and $2$ tenths.

Therefore, we will use the tenths notation (denominator $10$) and place $2$ in the numerator and $4$ in the wholes:

$4 \frac{2}{10}$

Convert the fraction $7.200$ to a simple fraction

Solution:

Let's ask ourselves – how do we read the fraction?

$7$ wholes and $200$ thousandths.

Therefore, we will use the thousandths notation (denominator $1000$), place $200$ in the numerator and $7$ as the whole number: $7 \frac{200}{1000}$

**Note** – if the fraction can be simplified, you can simplify it without changing its value:

$7 \frac{2}{10} = 7 \frac{200}{1000}$

And indeed we already know that: $7.200 = 7.2$

Convert the fraction $1.65$ to a simple fraction

Solution:

Let's ask ourselves – how do we read the fraction?

$1$ whole and $65$ hundredths

Therefore, we will use the hundredths notation – denominator $100$, place $65$ in the numerator and $1$ as the whole number.

We get:

$1 \frac{65}{100}$

We can simplify by dividing by $5$ and get: $1 \frac{13}{20}$

**Another example**

Convert the decimal $6.22$ to a mixed number

Solution:

Let's ask ourselves – how do we read the fraction?

$6$ wholes and $22$ hundredths

Therefore, we will use the hundredths notation - denominator $100$ and place $22$ in the numerator. Let's not forget to add $6$ wholes on the side and we get:
