Equivalent Fractions with Pizza

The video tutorial explains how to determine if two fractions are equivalent using a real-life example involving pizza. It demonstrates the mathematical process of proving equivalence by multiplying and dividing the numerator and denominator of fractions. The tutorial uses Alex's choice between two leftover pizzas to illustrate the concept, showing that 1/5 is equivalent to 2/10 and vice versa. The video emphasizes understanding the mathematical proof behind equivalent fractions.
