Steps to Convert 9/10 to a Decimal

Converting a fraction to a decimal involves a straightforward process:

1. Understand the Fraction: The fraction 9/10 means 9 divided by 10. The numerator (9) is the dividend, and the denominator (10) is the divisor.
2. Perform the Division: Divide the numerator (9) by the denominator (10). This is equivalent to asking, "How many times does 10 go into 9?"
3. Add a Decimal Point and Zero: Since 10 does not go into 9 evenly, you add a decimal point to the 9 and append a zero, making it 9.0.
4. Divide: 10 goes into 9.0 exactly once. Write the 1 above the decimal point.
5. Subtract: Subtract 10 from 9.0, which gives 0.0.
6. Result: The result of this division is 0.9. Which means, 9/10 = 0.9.

Scientific Explanation

The conversion from fraction to decimal relies on the base-10 number system. Now, a fraction like 9/10 inherently represents a division operation. The denominator (10) is a power of ten (10^1). When dividing by a power of ten, the decimal point in the quotient moves to the left by the same number of places as the exponent. Here, dividing by 10 (10^1) means moving the decimal point one place to the left in the numerator. Starting with 9.That's why 0, moving the decimal point one place left gives 0. 9. This principle explains why fractions with denominators that are powers of ten (like 10, 100, 1000) convert so cleanly to decimals with a specific number of decimal places (tenths, hundredths, thousandths, etc.).
