Fractions and decimals are two different ways of expressing numbers. Fractions consist of a numerator and a denominator, while decimals are written using a decimal point to separate the whole number part from the fractional part. Converting fractions to decimals is often necessary for performing mathematical operations and for everyday calculations.
In this article, we will explore the process of converting the fraction 5/8 to decimal. We will provide step-by-step instructions, highlight common mistakes to avoid, and discuss the pros and cons of using decimals over fractions. Additionally, we will include real-world examples and stories to illustrate the practical applications of converting fractions to decimals.
Converting 5/8 to decimal is a straightforward process that can be completed in just a few steps:
5 ÷ 8 = 0.625
Therefore, 5/8 as a decimal is 0.625.
When converting fractions to decimals, it is important to avoid common mistakes:
The following table provides additional examples of converting fractions to decimals:
Fraction | Decimal |
---|---|
1/2 | 0.5 |
1/4 | 0.25 |
3/4 | 0.75 |
1/5 | 0.2 |
2/5 | 0.4 |
3/5 | 0.6 |

Story 1:
A baker wants to divide a cake equally among 8 people. If the cake represents 5/8 of the whole, how much cake will each person receive?
Answer: Converting 5/8 to decimal, we get 0.625. Each person will receive 0.625 of the cake, or 62.5% of the cake.
Story 2:
A scientist measures the distance traveled by a particle as 3/4 of a meter. If the particle's speed is 2 meters per second, how far will it travel in 10 seconds?
Answer: Converting 3/4 to decimal, we get 0.75. The particle's speed is 2 meters per second, so it will travel 2 x 0.75 = 1.5 meters in 10 seconds.
Story 3:
A farmer has 1/2 of an acre of land to plant crops. If he plants corn on 3/5 of his land, what fraction of his land will be planted with corn?
Answer: Converting 1/2 and 3/5 to decimals, we get 0.5 and 0.6, respectively. The farmer will plant corn on 0.6 x 0.5 = 0.3 acres, which is 30% of his land.
