Converting Fractions to Decimals: A Comprehensive Guide

Fractions and decimals are two different ways of representing numerical values. Fractions use a numerator and denominator to represent a portion of a whole, while decimals use a decimal point to represent a number that is less than one. Converting fractions to decimals can be a useful skill in various situations, such as in mathematics, science, and finance.

Step-by-Step Approach to Converting Fractions to Decimals

1. Divide the numerator by the denominator: Perform long division or use a calculator to divide the numerator by the denominator.

2. Write the result as a decimal: The result of the division is the decimal representation of the fraction.

Stories and Lessons Learned

Story 1: A baker needs to measure out 3/4 cup of flour for a recipe. To convert this to a decimal, they divide 3 by 4 using long division:

     0.75
4 ) 3.00
    28
     200

Therefore, 3/4 cup of flour is equivalent to 0.75 cups.

Lesson Learned: Converting fractions to decimals can help in precise measurements and calculations.

Story 2: A student needs to convert the fraction 5/8 to a decimal to enter it into a calculator. They divide 5 by 8 using a calculator:

5 ÷ 8 = 0.625

Therefore, 5/8 is equivalent to the decimal 0.625.

Lesson Learned: Converting fractions to decimals makes them easier to use in electronic devices and calculations.
