0.8 as a fraction is equal to 4/5. To convert a decimal to a fraction, multiply the decimal by 10, 100, 1000, and so on and count how many zeros are after the decimal point. The number of zeroes is the denominator. So, 0.8 x 100 = 80. 80/100 = 4/5.

Introduction
In mathematics, a fraction is a number that represents a part of a whole. It is written as a ratio of two numbers, with the numerator (top number) representing the number of parts, and the denominator (bottom number) representing the total number of parts. For example, if there are eight pieces in a whole, then each piece would be represented by 1/8.
The value of a fraction can be represented on a number line. The position of a point on the line represents the value of the fraction. For example, if we consider the unit interval [0,1], then we can see that 0.8 lies somewhere between 0 and 1. We can also see that it is closer to 1 than it is to 0. This means that 0.8 is greater than 0 but less than 1, or equivalently, that 0 < 0.8 < 1. When we convert a decimal like 0.8 into a fraction, we are really just finding an equivalent fraction with a denominator of 10, 100, 1000 etc. We do this by multiplying both the numerator and denominator by the same number until we get an integer in the numerator and a power of 10 in the denominator (i.e., 10, 100, 1000 etc.). For example: 0
What is 0.8 as a Fraction?
0.8 can be written as a fraction in several ways. The easiest way is to divide 8 by 10 to get 0.8 as a fraction. However, this is not the only way to write 0.8 as a fraction. You can also divide 8 by 100 to get 0.08 as a fraction.
Decimals and fractions
When we talk about “how much” of something, we are talking about quantity. In the English language, quantity can be measured using units like cups, tablespoons, or hours. But sometimes we need to be more specific and use numbers to talk about quantity.
In the metric system, the standard unit for measuring quantity is the meter (m). But sometimes we need to use smaller or larger units like centimeters (cm) or kilometers (km). The metric system also uses a standard unit for mass, which is the kilogram (kg).
We can use decimal notation to express quantities that are less than one meter or kilogram. For example, 0.8 m means “eight tenths of a meter” and 0.35 kg means “three and a half tenths of a kilogram.”
We can also use decimal notation to express quantities that are greater than one meter or kilogram. For example, 2.5 m means “two and a half meters” and 5.3 kg means “five point three kilograms.”
When we want to express a quantity as a number without using any units, we can use fractional notation. In fractional notation, 0.8 would be written as 8/10 and 0.35 would be written as 7/20.
Converting fractions to decimals
To convert a fraction to a decimal, divide the numerator (top number) by the denominator (bottom number).
For example, if someone plugs in the fraction ¾ and hits the “=” button on a calculator, the answer would return as the decimal .75 on the calculator. In other words, fraction ¾ is equal to decimal .75.
It can be helpful to think of fractions as division equations. For example:
-The fraction ¾ can be thought of as the division equation ¾ ÷ 1 = .75
-The fraction ½ can be thought of as the division equation ½ ÷ 1 = .50
-The fraction ⅓ can be thought of as the division equation ⅓ ÷ 1 = .33
-And so on…
Conclusion
To conclude, 0.8 is equal to 4/5 as a fraction. This means that if you have 0.8 of something, it is the same as having 4 out of 5 of that thing.
