Understanding the Fraction ¹⁵⁄₁₆

Before diving into the conversion process, it’s essential to understand what the fraction ¹⁵⁄₁₆ represents. A fraction consists of a numerator (the top number) and a denominator (the bottom number). In this case, the numerator is 15, and the denominator is 16. This fraction indicates that you have 15 parts out of a total of 16 parts.

Converting ¹⁵⁄₁₆ to a Decimal

To convert the fraction ¹⁵⁄₁₆ to a decimal, you need to perform a division operation. Here are the steps to follow:

Divide the numerator (15) by the denominator (16).
Use long division or a calculator to find the quotient.

Let’s break down the division process:

15 ÷ 16 = 0.9375

So, ¹⁵⁄₁₆ as a decimal is 0.9375.

Step-by-Step Division Process

To better understand the conversion, let’s go through the division process step by step:

Set up the division: 15 ÷ 16.
Since 15 is less than 16, place a decimal point and a zero in the quotient.
Multiply 15 by 10 to get 150.
Divide 150 by 16. The quotient is 9, with a remainder of 6.
Bring down a zero and divide 60 by 16. The quotient is 3, with a remainder of 12.
Bring down another zero and divide 120 by 16. The quotient is 7, with a remainder of 8.
Bring down another zero and divide 80 by 16. The quotient is 5, with no remainder.

Thus, the decimal equivalent of ¹⁵⁄₁₆ is 0.9375.

📝 Note: The decimal 0.9375 is a terminating decimal, meaning it ends after a certain number of decimal places. This is because 16 is a power of 2, and dividing by powers of 2 results in terminating decimals.
