15/3 as a Decimal

Professor Greenline Explaining Math Concepts

It is a simple question on decimal conversion. Firstly, we have to learn fractions and decimals. A fraction represents a part of a whole. It has two parts: the numerator (number on the top), here, 15, represents how many parts out of the whole. The denominator (number below) shows how many parts make up the whole, here it is 3. A decimal is a way to represent a number that is not whole, using a (.) or a decimal point to separate the whole part from the fraction part. The numbers to the left of the decimal point represent the whole, and those to the right represent the fractional part.

What is 15/3 as a decimal?

15/3 as a decimal

 

 

Answer

15/3 in decimals can be written as 5. It is a terminating decimal, showing the division results in a whole number.

 

Explanation

To get 15/3 in decimal, we will use the division method. Here, 15 is larger than 3, so we can divide directly without needing a decimal. Let's see the step-by-step breakdown of the process:

 

Step 1: Identify the numerator and denominator because the numerator (15) will be taken as the dividend and the denominator (3) will be taken as the divisor.

 

Step 2: Divide 15 by 3. Let's see how many times 3 fits into 15.

 

Step 3: 15 is a multiple of 3, specifically 3 × 5 = 15.

 

Step 4: Write 5 in the quotient place as 3 goes into 15 exactly 5 times.

 

Step 5: Subtract 15 from 15, which gives 0 as a remainder. The division process completes with no remainder, indicating a terminating decimal.

 

The answer for 15/3 as a decimal will be 5.
