Simplifying Fractions and Factorization

The video tutorial explains how to simplify fractions to their lowest terms using two methods: prime factorization and division. It begins with an introduction to the concept of simplifying fractions, followed by detailed examples using both methods. The prime factorization method involves breaking down numbers into their prime factors to identify common factors, while the division method involves dividing the numerator and denominator by common factors until no further simplification is possible. The tutorial provides two examples to illustrate both methods, highlighting their benefits and challenges.

What is the main goal when simplifying a fraction?

• To convert it into a decimal

• To make the denominator smaller

• To ensure the only common factor is one

• To make the numerator larger

What is the prime factorization of 60?

• 3 x 3 x 5

• 2 x 2 x 3 x 5

• 2 x 2 x 2 x 5

• 2 x 3 x 5
