It is a simple question on decimal conversion. Firstly, we have to learn fractions and decimals. A fraction represents a part of the 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 the whole, here it is 30. A decimal is a way to represent a number that is not whole, using a (.) or a decimal 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 15/30 as a decimal?

$15/30 as a decimal$

Answer

15/30 in decimals can be written as 0.5. It is a terminating decimal, meaning it does not repeat infinitely.

Explanation

To get 15/30 in decimal, we will use the division method. Here, 15 is smaller than 30, so we will perform division. 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 (30) will be taken as the divisor.

Step 2: As 15 is smaller than 30, it can't be divided once without a decimal, so we consider the fraction as a division of 15 by 30.

Step 3: 15 divided by 30 can be simplified to 1/2, which equals 0.5 when expressed as a decimal.

Step 4: The division of 15 by 30 results in 0.5, and there is no remainder.

The answer for 15/30 as a decimal is 0.5.
