What Is 1.27?

1.27 is a decimal number consisting of two parts: the whole number part (1) and the fractional part (0.27). In this decimal, "1" is the whole number, and "0.27" represents a portion of a whole.

Breaking Down the Decimal

In the decimal 1.27:

• The "1" indicates that there is one whole.
• The "27" after the decimal point means that there are 27 hundredths because it occupies the hundredths place.

The fractional representation of the decimal 1.27 can be understood as:

• Whole number: 1
• Fractional part: 0.27, which is 27/100.

How to Convert 1.27 to a Fraction

Step 1: Separate the Whole Number from the Decimal

The first step in converting the decimal 1.27 to a fraction is to separate the whole number from the decimal. Here, we have:

• Whole number: 1
• Decimal: 0.27

Step 2: Convert the Decimal to a Fraction

Next, convert the decimal part (0.27) into a fraction. To do this, place the decimal number over its place value. Since 0.27 has two decimal places, it is written as:

[ 0.27 = \frac{27}{100} ]

Step 3: Combine the Whole Number and the Fraction

Now that we have our whole number and fractional part, we can write the entire number as a mixed number:

[ 1.27 = 1 + \frac{27}{100} = \frac{100}{100} + \frac{27}{100} = \frac{127}{100} ]

Thus, the decimal 1.27 can be expressed as the fraction:

[ \frac{127}{100} ]

Simplifying the Fraction

It’s important to check if the fraction can be simplified. To simplify a fraction, you need to find the greatest common divisor (GCD) of the numerator and denominator.

Steps to Simplify

1. Identify the GCD: The numerator is 127 and the denominator is 100. The GCD of 127 and 100 is 1, as 127 is a prime number.
2. Simplify the Fraction: Since the GCD is 1, the fraction cannot be simplified further.

Thus, the simplified form of the fraction for 1.27 is still:

[ \frac{127}{100} ]

Final Fraction Representation

The final representation of the decimal 1.27 as a fraction is:

[ \frac{127}{100} ]

This means that 1.27 is equivalent to 127 hundredths.
