Understanding the decimal: “0.72”

A decimal number has an integer and fractional parts. The decimal point separates the two. The integer is to the left, the fraction to the right. For example, in 0.72, 0 is the integer and 72 is the fraction.

Conversion Explanation:

  1. For the numerator:
    • We start with the number 0.72.
    • By removing the decimal point, we derive the numerator as 72.
  2. For the denominator:
    • Each position after the decimal represents a division by 10.
    • Thus, having 2 positions after the decimal equates to 100 or 102.
  3. Factors:
    • The factors for the numerator and the denominator are numbers that can evenly divide each of them.
    • For instance, the factors of 72 include 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, and 72.
    • The factors of 100 comprise 1, 2, 4, 5, 10, 20, 25, 50, and 100.
  4. Greatest Common Divisor (GCD):
    • It's the largest number that can evenly divide both the numerator and the denominator.
    • In this instance, the GCD for 72 and 100 is 4.

The factors of 72 are:

1 2 3 4 6 8 9 12 18 24 36 72

The factors of 100 are:

1 2 4 5 10 20 25 50 100

Conversion formula (equation):

0.72=0.721=0.72 × 1001 × 100=72100=72÷4100÷4=1825

Solution:

0.72 = 1825

What is a decimal?

A decimal is a numeral system with a point. This point divides the integer from its fractional part. It provides a straightforward way to express and work with values less than one.

What is a fraction?

A fraction is a mathematical expression of two parts: the numerator on top and the denominator below. It represents partial values, showcasing relationships or comparisons.

A fast guide to the conversion:

Numbers exist in different formats: decimals, fractions, and percentages. Today, we'll convert the decimal 0.72 into its fractional form. This conversion shows the core essence of the number. And making mathematical operations more intuitive.

Step-by-step solution:

  • Step 1: Laying the groundwork. Before diving into conversion, let's frame our decimal as a fraction over 1. This offers a clean slate, making the subsequent steps systematic. 0.72 = 0.721
  • Step 2: Gauging the decimal's depth. Decimals vary. Some are short; others are long. Our focus? The number of digits after the decimal point. For 0.72, we have three digits. This insight nudges us to elevate our fraction by a factor of 10 for each digit. Factor = 102 = 100
  • Step 3: Amplifying the fraction. Taking our coefficient, it's time to strengthen both the numerator and denominator. The intent? To equalize the fraction by the depth of the decimal. 0.72 × 1001 × 100 = 72100
  • Step 4: Simplifying. Elegance lies in simplicity. Our mission now is to shorten the 72100. This requires seeking common divisors. Here, 4 is our ally, dividing both parts seamlessly. 72 ÷ 4100 ÷ 4 = 1825

Conclusion:

The decimal 0.72, when unfurled and explored, translates seamlessly into the fraction 0.72/1. This manual provides an introduction to numbers and deepens number skills. Such conversions, though seemingly elementary, pave the way for advanced mathematical prowess.
