Fractions and decimals are two ways to represent parts of a whole. Understanding how to convert fractions to decimals is essential for mathematical calculations. One common fraction is 1/8th, which can be expressed as a decimal with ease. This article will guide you through the process of converting 1/8th to decimals, providing insightful examples and practical applications.
Step 1: Understand Decimal Place Value
Decimals are based on powers of 10, where each digit to the right of the decimal point represents a smaller place value. The first digit represents tenths, the second digit represents hundredths, and so on.
Step 2: Convert 1/8th to a Fraction with a Denominator of 10
To convert 1/8th to a decimal, we need to change the denominator to a power of 10. In this case, we can multiply both the numerator and denominator by 5, giving us 5/40.
Step 3: Remove the Common Factor
Both the numerator and denominator have a common factor of 5. We can cancel these out, leaving us with 1/8.
Step 4: Place the Decimal Point
Since we multiplied the denominator by 10, we need to move the decimal point one place to the right in the numerator. This gives us 0.125.
Therefore, 1/8th as a decimal is 0.125.
Story 1: The Pizza Party
A group of friends ordered a large pizza that was cut into 8 slices. Each friend wanted to eat 1/8th of the pizza. To determine how many slices each person should get, they converted 1/8th to a decimal. By dividing 1 by 8, they found that 0.125 represented 1/8th. Therefore, each friend should receive 0.125 * 8 = 1 slice of pizza.
Lesson: Converting fractions to decimals can help solve real-world problems involving the division of items.
Story 2: The Science Experiment
In a science experiment, students measured the length of a plant in centimeters. The measurement was 12.5 cm, which could also be expressed as 125 / 10. By converting the fraction 125 / 10 to a decimal, they found 12.5. This clarified that the plant's length was 12.5 cm.
Lesson: Decimals are useful for representing fractional measurements in scientific and mathematical contexts.
