Converting Repeating Decimals to Fractions

The video tutorial explains how to convert repeating decimals into fractions using two examples. The first example demonstrates the conversion of 0.86 with the six repeating, while the second example covers 3.152 with the five and two repeating. Each example follows a step-by-step process involving setting the decimal equal to a variable, multiplying to shift the decimal, forming equations, and solving for the variable to find the fraction equivalent. The tutorial emphasizes checking the results using a calculator.
