66.666 as a Fraction

Professor Greenline Explaining Math Concepts

Numbers can be categorized into different types. A fraction is one such type. It is always represented in the form of p/q, where p is the numerator and q is the denominator. A fraction represents a whole and a fractional part. Decimals represent the fractional part of numbers. For example, 1/2. Numbers in decimal form are expressed with a decimal point (.), for example, 66.666. We are going to learn how to convert a decimal to a fraction.

What is 66.666 as a Fraction?

66.666 as a fractionAnswer

 

The answer for 66.666 as a fraction will be 200/3.

 

Explanation

 

Converting a decimal to a fraction is a task for students that can be done easily. You can follow the steps mentioned below to find the answer.

 

Step 1: Firstly, any decimal number should be converted to a fraction for easy calculation. Here, 66.666 is the number on the numerator and the base number 1 will be the denominator. Then, 66.666 becomes 66.666/1.

 

Step 2: To remove the repeating decimal from a fraction, you need to multiply both the numerator and the denominator by 1000 (because the repeating sequence is three digits long). 66.666/1 × 1000/1000 = 66666/1000

 

Step 3: Here, identify the repeating part (666) and subtract to find the fraction. For repeating decimals, subtract the non-repeating part (66) multiplied by 10 from the repeating part. (66666 - 66) / (1000 - 10) = 66600/990

 

Step 4: Simplify the fraction by finding the greatest common divisor (GCD) of 66600 and 990, which is 330. 66600/990 ÷ 330/330 = 200/3

 

Thus, 66.666 can be written as a fraction 200/3.
