What is 0.8 as a fraction?

0.8 is a decimal number that represents eight-tenths. To convert it into a fraction, we can follow these steps:

  1. Write the decimal as a fraction with a denominator of 10. Since the decimal has one digit after the decimal point, we write it as 8/10.

  2. Simplify the fraction if possible. Both 8 and 10 are divisible by 2. Dividing both numerator and denominator by 2, we get 4/5.

Therefore, 0.8 can be expressed as the fraction 4/5.

Why are fractions important?

Fractions are essential in mathematics and everyday life. They represent parts of a whole and allow us to divide quantities, express ratios, and perform calculations with proportions. Understanding fractions helps us to:

  • Solve problems involving quantities: For example, dividing a cake into equal slices or calculating the amount of ingredients needed for a recipe.
  • Compare and order numbers: We can easily compare fractions with the same denominator, and we can use cross-multiplication to compare fractions with different denominators.
  • Represent proportions: Fractions can be used to represent proportions, such as the ratio of boys to girls in a classroom or the percentage of students who passed a test.

By understanding how to convert decimals to fractions, we gain a deeper understanding of numbers and their relationships.
