How to Convert Decimals to Fractions Using a 3-Step Method

Mashup Math

This instructional video provides a clear, step-by-step guide on how to convert terminating decimals into fractions. Using a systematic 3-step process, the video demonstrates the mathematical procedure of rewriting the decimal with a denominator of 1, multiplying by powers of 10 to remove the decimal point, and finally simplifying the resulting fraction to its lowest terms. The content is presented visually with on-screen text and animations, making it suitable for visual learners. The video explores key mathematical themes including rational numbers, place value, and fraction simplification. It specifically focuses on the relationship between the number of decimal places and the power of 10 required for conversion (e.g., two decimal places requires multiplying by 100). Two complete examples are worked through in detail: converting 0.25 into 1/4 and converting 0.375 into 3/8. For educators, this video serves as an excellent direct instruction tool or review resource for upper elementary and middle school math students. It breaks down a multi-step algorithmic process into manageable chunks, making it ideal for students who struggle with the mechanics of conversion. The clear visual distinction between steps helps scaffold learning, allowing teachers to pause and check for understanding before moving to the simplification phase.
