Questions & Answers

Q: What is a numerator and denominator in a fraction?

The numerator represents the number of parts being considered, while the denominator represents the total number of parts in the whole.

Q: How can fractions be expressed as decimals and percentages?

Fractions can be converted to decimals by dividing the numerator by the denominator. To get a percentage, the decimal can be multiplied by 100.

Q: What is the difference between proper and improper fractions?

Proper fractions have a numerator smaller than the denominator, while improper fractions have a numerator larger than the denominator.

Q: How can improper fractions be converted to mixed numbers?

Improper fractions can be written as mixed numbers by dividing the numerator by the denominator. The whole number part is obtained by the division, and the remaining fraction is written as a fraction with the same denominator.

Summary & Key Takeaways

• Fractions are used to describe parts of a whole, with the numerator representing the number of parts and the denominator representing the total number of parts.

• Fractions can be thought of as division, where the numerator is divided by the denominator to get a decimal or percentage value.

• There are three types of fractions: proper fractions, where the numerator is smaller than the denominator; improper fractions, where the numerator is larger than the denominator; and mixed numbers, which are a combination of whole numbers and fractions.
