Converting .8 to a Fraction
To convert .8 to a fraction, we start by considering its place value. Since .8 is in the tenths place, we can express it as 8⁄10. This fraction represents the decimal .8 in its simplest form. However, it is essential to note that fractions can often be simplified further by dividing both the numerator and the denominator by their greatest common divisor (GCD).
Simplifying the Fraction
In the case of 8⁄10, the GCD of 8 and 10 is 2. By dividing both the numerator and the denominator by 2, we get 4⁄5. Therefore, the fraction equivalent of .8 is 4⁄5. This simplified form is essential in mathematics, as it allows for easier comparison and manipulation of fractions.
| Decimal | Fraction | Simplified Fraction |
|---|---|---|
| .8 | 8/10 | 4/5 |
