What Is a Fraction?
Let’s start with the basics. A fraction is a way to represent a part of a whole. It consists of two numbers separated by a line or slash. The number above the line is called the numerator, and the number below the line is called the denominator. Fractions are typically written in the form of a/b, where ‘a’ is the numerator, and ‘b’ is the denominator.
Expressing 0.6875 as a Fraction
To express 0.6875 as a fraction, we need to understand its decimal representation. It’s a decimal number, and its value is greater than 0 but less than 1. To convert it into a fraction, we can follow these steps:
Step 1: Identify the Decimal Place Value
0.6875 has four digits after the decimal point. To convert it into a fraction, we’ll place it over a power of 10. In this case, we’ll use 10000 because there are four digits.
Step 2: Write the Fraction
Now, we can write 0.6875 as a fraction:
0.6875 = 6875/10000
Step 3: Simplify the Fraction
To simplify the fraction, we can divide both the numerator and denominator by their greatest common factor, which is 125:
