How can you write the decimal 0.95 as a fraction?
The Correct Answer and Explanation is:
To write the decimal 0.95 as a fraction, follow these steps:
Answer:
0.95=19200.95 = \frac{19}{20}0.95=2019
Explanation:
To convert a decimal to a fraction, begin by identifying the place value of the last digit in the decimal. In 0.95, the digit 5 is in the hundredths place because there are two digits after the decimal point. This means that the decimal can initially be written as:0.95=951000.95 = \frac{95}{100}0.95=10095
Next, simplify the fraction by dividing both the numerator and denominator by their greatest common divisor (GCD). The GCD of 95 and 100 is 5.95÷5100÷5=1920\frac{95 \div 5}{100 \div 5} = \frac{19}{20}100÷595÷5=2019
Therefore, 0.95 simplifies to the fraction:1920\frac{19}{20}2019
This is the simplest form because the numerator and denominator no longer have any common factors other than 1.
Understanding the Process:
When converting a decimal to a fraction, the number of digits after the decimal determines the initial denominator:
- One digit → denominator is 10
- Two digits → denominator is 100
- Three digits → denominator is 1000, and so on
In this case, 0.95 has two digits after the decimal, so start with 100 as the denominator.
The goal in simplifying is to reduce the fraction by dividing both the top and bottom by their largest common factor. This ensures the fraction is expressed in its lowest terms, which is the standard practice in mathematics.
This method works for any terminating decimal, and understanding it helps in building number sense, especially in recognizing decimal-to-fraction conversions, simplifying ratios, and working with proportions.
