Detailed Explanation

A mixed number consists of a whole number and a proper fraction. In the case of 9 3/5, the whole number is 9, and the fractional part is 3/5. To convert this to a decimal, we focus on the fractional component. The fraction 3/5 represents three parts out of five equal divisions of a whole. Converting fractions to decimals involves division: the numerator (3) is divided by the denominator (5).

When performing this division (3 ÷ 5), we get 0.6. Adding this decimal value to the whole number 9 results in 9.6. This means 9 3/5 as a decimal is 9.6. This conversion is straightforward once you understand the relationship between fractions and decimals. Fractions represent parts of a whole, while decimals express those parts in a base-10 system, making them easier to use in calculations and comparisons.

Step-by-Step Conversion Process

1. Identify the Whole Number and Fraction: Start by separating the whole number (9) from the fractional part (3/5).
2. Convert the Fraction to a Decimal: Divide the numerator (3) by the denominator (5). Since 3 is less than 5, we add a decimal point and zeros to continue the division.
   • 3.0 ÷ 5 = 0.6.
3. Combine the Results: Add the decimal value of the fraction (0.6) to the whole number (9).
   • 9 + 0.6 = 9.6.

This method works for any mixed number. Here's one way to look at it: converting 2 1/4 would involve dividing 1 by 4 to get 0.In practice, 25, then adding to 2 for a total of 2. Worth adding: 25. Practicing these steps builds confidence in handling more complex conversions.
