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.
