Fractions and decimals are two fundamental concepts in mathematics that can often leave learners puzzled. Among these, converting fractions to decimals is an essential skill that unlocks a deeper understanding of numbers. In this comprehensive guide, we will embark on a detailed exploration of 1/8th as a decimal, enriching our mathematical vocabulary and equipping ourselves with practical applications.
A decimal is a representation of a number that uses a decimal point to separate the whole number part from the fractional part. This numerical notation allows us to express numbers with greater precision and flexibility. Converting a fraction to a decimal involves dividing the numerator by the denominator, carrying out the operation until the desired level of accuracy is achieved.
1/8th as a decimal is 0.125.
Mathematical Proof:
1/8 = 1 / 8
= 0.125
This can also be verified by using a calculator or long division method. By placing 1 as the dividend and 8 as the divisor, we obtain a quotient of 0.125, confirming our result.
Converting 1/8th to a decimal has numerous practical applications across various fields:
Fraction | Decimal |
---|---|
1/2 | 0.5 |
1/4 | 0.25 |
1/8 | 0.125 |
1/10 | 0.1 |
1/16 | 0.0625 |
Step 1: Understand the Concept
Grasp that a decimal is a representation of a number using a decimal point to separate the whole number part from the fractional part.
Step 2: Divide the Numerator by the Denominator
Divide the numerator (1) by the denominator (8), carrying out the division until the desired accuracy is achieved.
Step 3: Place the Decimal Point
After dividing, the decimal point should be placed in the quotient directly above the division line.
Step 4: Obtain the Decimal Equivalent
Complete the division to obtain the decimal equivalent of 1/8th, which is 0.125.
Story 1:
In a carpentry workshop, a carpenter needs to cut a wooden plank to a length of 7/8th of an inch. Using a measuring tape calibrated in decimals, he converts 7/8th to 0.875 inches, ensuring the plank is cut to the precise length required.
Lesson: Converting fractions to decimals allows for accurate measurements and calculations in various practical applications.
Story 2:
A chemist prepares a solution for an experiment that requires a concentration of 15%. To achieve this, the chemist needs to add 1/8th of a liter of a concentrated chemical to a larger volume of water. By converting 1/8th to 0.125 liters, the chemist accurately measures and adds the required amount of concentrated chemical.
Lesson: Decimals enable precise quantification of substances in chemistry and other scientific disciplines.
Story 3:
A business owner wants to calculate the percentage of sales achieved in a quarter, knowing that the total sales were $10,000. To determine the percentage, the owner converts 1/8th to 0.125 and calculates that the sales achieved represent 12.5% of the total sales target.
Lesson: Understanding 1/8th as a decimal is essential for calculating percentages accurately in business and other fields.
Converting fractions to decimals, particularly 1/8th to 0.125, is a fundamental skill with wide-ranging applications. By mastering this concept, we unlock the ability to perform precise measurements, quantify substances accurately, calculate percentages effectively, and solve complex mathematical problems. Embracing the strategies outlined in this guide and avoiding common pitfalls will empower you to confidently navigate the world of fractions and decimals with ease.
