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.
