decimal of 7/8

Understanding the Decimal of 7/8

In mathematics, fractions are a fundamental concept that represents a part of a whole. They are commonly used to express quantities that are not whole numbers. One important aspect of fractions is their decimal representation, which allows us to express them in a different form. In this blog, we will explore the decimal representation of the fraction 7/8 and discuss various methods to solve it.

The Decimal of 7/8

Before diving into the methods to solve the decimal of 7/8, let's first find the answer. The decimal representation of 7/8 is 0.875.

Methods to Solve the Decimal of 7/8

There are several ways to solve the decimal of 7/8. Let's explore two common methods:

Method 1: Long Division

To solve the decimal of 7/8 using long division, follow these steps:

1. Write down the fraction 7/8.
2. Divide 7 by 8. The quotient is 0 and the remainder is 7.
3. Bring down the next digit, which is 0, and divide 70 by 8. The quotient is 8 and the remainder is 6.
4. Bring down the next digit, which is 0, and divide 60 by 8. The quotient is 7 and the remainder is 4.
5. Bring down the next digit, which is 0, and divide 40 by 8. The quotient is 5 and the remainder is 0.
6. The division process ends here since there are no more digits to bring down.
7. The final quotient is 0.875, which represents the decimal of 7/8.

Method 2: Denominator as 1000

Another method to solve the decimal of 7/8 is by converting the fraction to an equivalent fraction with a denominator of 1000. Follow these steps:

1. Multiply both the numerator and denominator of 7/8 by 125 to get an equivalent fraction with a denominator of 1000.
2. The equivalent fraction is (7 * 125) / (8 * 125) = 875 / 1000.
3. The decimal representation of 875/1000 is 0.875.

Solved Examples

Let's explore a few more examples to solidify our understanding of the decimal of 7/8:

1. Example: Find the decimal representation of 21/8.

   Solution: Using long division, we get 2.625 as the decimal representation of 21/8.

2. Example: Convert the fraction 5/8 to a decimal.

   Solution: Using the denominator as 1000, we get 0.625 as the decimal representation of 5/8.

3. Example: Solve the decimal of 14/8.

   Solution: Using long division, we get 1.75 as the decimal representation of 14/8.

Understanding Fractions in Mathematics

In mathematics, fractions represent a part of a whole or a division of quantities. They consist of a numerator and a denominator, separated by a fraction bar. Fractions can be proper (numerator < denominator), improper (numerator > denominator), or mixed numbers (a whole number combined with a proper fraction).

Symbols Used to Represent Fractions

Fractions are represented using the fraction bar (/) or a horizontal line. For example, 7/8 or 7-8.

Types of Fractions

There are various types of fractions, including:

1. Proper fractions: Fractions where the numerator is less than the denominator, such as 3/4.
2. Improper fractions: Fractions where the numerator is greater than or equal to the denominator, such as 5/4.
3. Mixed numbers: A combination of a whole number and a proper fraction, such as 1 3/4.

Components of Fractions

Fractions consist of two main components:

1. Numerator: The number above the fraction bar, representing the part of the whole or the dividend in a division.
2. Denominator: The number below the fraction bar, representing the whole or the divisor in a division.

Understanding Decimals

Decimals are another way to represent fractions or numbers that are not whole. They are based on powers of 10 and use a decimal point to separate the whole number part from the fractional part.

Symbol Used to Represent Decimals

Decimals are represented using a decimal point (.) placed between the whole number part and the fractional part. For example, 0.875.

Components of Decimals

Decimals consist of two main components:

1. Whole number part: The part of the decimal to the left of the decimal point.
2. Fractional part: The part of the decimal to the right of the decimal point.

Types of Decimals

There are various types of decimals, including:

1. Terminating decimals: Decimals that have a finite number of digits after the decimal point, such as 0.5 or 0.75.
2. Repeating decimals: Decimals that have a repeating pattern of digits after the decimal point, such as 0.333... or 0.142857142857...
