30.8 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 both 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 (.), such as 30.8. We are going to learn how to convert a decimal to a fraction.

30.8 as a fraction

 

Answer

 

The answer for 30.8 as a fraction is 154/5.

 

Explanation

 

Converting a decimal to a fraction is a straightforward process for students. You can follow the steps mentioned below to find the answer.

 

Step 1: Firstly, any decimal number should be expressed as a fraction for easy calculation. Here, 30.8 is the number in the numerator, and the base number 1 will be the denominator. Thus, 30.8 becomes 30.8/1.

 

Step 2: To eliminate the decimal from the fraction, you need to multiply both the numerator and denominator by 10 (because there is only 1 decimal place). 30.8/1 × 10/10 = 308/10

 

Step 3: Here, 2 is the GCD of 308 and 10. Now, to simplify the fraction, divide the numerator and denominator by 2. 308/10 = 154/5 Hence, 30.8 is in the form of the fraction 154/5.

 

Thus, 30.8 can be written as a fraction 154/5.
