15.3 as a Fraction

Professor Greenline Explaining Math Concepts

Numbers can be categorized into different types. A fraction is one such type and is always represented in the form of p/q, where p is the numerator and q is the denominator. A fraction can represent both whole and fractional parts of a number. Decimals are another way to express the fractional part of numbers. For example, 1/2 can be represented in decimal form as 0.5. In this guide, we will learn how to convert the decimal 15.3 into a fraction.

15.3 as a fraction

 

 

Answer

The answer for 15.3 as a fraction is 153/10.

 

Explanation

Converting a decimal to a fraction can be done following these steps:

 

Step 1: Convert the decimal number to a fraction. Here, 15.3 is the number, and it can initially be represented with the base number 1 as 15.3/1.

 

Step 2: To eliminate the decimal, multiply both the numerator and the denominator by 10 (since there is only one decimal place). 15.3/1 × 10/10 = 153/10

 

Step 3: In this case, the fraction 153/10 is already in its simplest form since the greatest common divisor (GCD) of 153 and 10 is 1.

 

Thus, 15.3 can be written as a fraction 153/10.
