Understanding Mixed Numbers

A mixed number is a combination of a whole number and a fraction. It is written in the form of $$a \frac{b}{c}$$, where $$a$$ is the whole number part, and $$\frac{b}{c}$$ is the fractional part. In this article, we will learn how to convert a mixed number to a decimal.

Converting $$8 \frac{19}{20}$$ to a Decimal

To convert the mixed number $$8 \frac{19}{20}$$ to a decimal, we need to follow these steps:

Step 1: Convert the Fraction to a Decimal

First, we need to convert the fractional part $$\frac{19}{20}$$ to a decimal. To do this, we divide the numerator (19) by the denominator (20).

\frac{19}{20} = 0.95

Step 2: Add the Whole Number

Now that we have the decimal equivalent of the fractional part, we can add it to the whole number part.

8 + 0.95 = 8.95

Conclusion

In this article, we learned how to convert a mixed number to a decimal. We used the example of $$8 \frac{19}{20}$$ to demonstrate the process. By following the steps outlined above, we can convert any mixed number to a decimal.
