Simplifying Fractions and Divisors

The video tutorial demonstrates how to simplify fractions by identifying common divisors. It provides three examples: simplifying 4/8 by dividing both numbers by 4, simplifying 25/45 by dividing both numbers by 5, and simplifying 12/100 using multiple steps by dividing by 2 twice. The tutorial emphasizes the importance of finding the greatest common divisor to simplify fractions efficiently.

What is the first step in simplifying a fraction?

• Multiply the numerator and denominator
