This is a simple question on time conversion. Firstly, we need to understand how to convert time into decimal format. Time is typically measured in hours, minutes, and seconds.

How do you express 15 seconds as a decimal?
Answer
15 seconds can be expressed as 0.3 minutes in decimal form.
Explanation
To convert 15 seconds into a decimal, we need to express it as a fraction of a minute. There are 60 seconds in a minute. Therefore, 15 seconds is 15/60 of a minute. Performing the division gives us:
Step 1: Identify the number of seconds (15) and the total seconds in a minute (60).
Step 2: Express the fraction as 15/60.
Step 3: Simplify the fraction by dividing both the numerator and denominator by the greatest common divisor, which is 15.
Step 4: 15 ÷ 15 = 1 and 60 ÷ 15 = 4, so the simplified fraction is 1/4.
Step 5: Convert the fraction to a decimal by dividing the numerator by the denominator: 1 ÷ 4 = 0.3.
Thus, 15 seconds is equivalent to 0.3 minutes in decimal form.
