## Why Convert Decimals to Fractions? While calculators and digital tools often use **decimals**, many physical tools — such as tape measures, drill bits, and conduit benders — are marked in **fractions**. Being able to convert between the two ensures accuracy when working with: - Material measuring and cutting - Converting meter readings into usable values - Matching decimal-based specifications to fraction-based tools ## Step-by-Step: How to Convert ### Step 1: Identify the Place Value Every decimal can be expressed as a fraction of 10, 100, 1000, and so on. Example: $0.75 = \frac{75}{100}$ ### Step 2: Simplify the Fraction $\frac{75}{100} = \frac{3}{4}$ ## Common Decimal to Fraction Conversions | Decimal | Fraction | |---------|----------| | 0.5 | 1/2 | | 0.25 | 1/4 | | 0.75 | 3/4 | | 0.125 | 1/8 | | 0.375 | 3/8 | | 0.625 | 5/8 | | 0.875 | 7/8 | | 0.333 | 1/3 (approx.) | | 0.666 | 2/3 (approx.) | These conversions appear frequently in blueprints, schematics, and part specifications. ## Real-World Example: Conduit Stub Measurement Suppose you measure **0.625 inches** on your digital caliper, but your bender uses fractional markings. Convert: $0.625 = \frac{625}{1000} = \frac{5}{8}$ You would mark your bend at **5/8 inch** so the physical work matches the digital reading. ## Try It Yourself 1. Convert 0.5 to a fraction. 2. Convert 0.875 to a fraction. 3. Convert 0.2 to a fraction and simplify.
