Understanding the decimal: “3.84”

A decimal number consists of an integer part and a fractional part, separated by a decimal point. The integer part is on the left, and the fractional part is on the right. For example, in 3.84, 3 is the integer part and 84 is the fractional part.

Conversion Explanation:

  1. For the numerator:
    • We start with the number 3.84.
    • By removing the decimal point, we derive the numerator as 384.
  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 384 include 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, and 384.
    • 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 384 and 100 is 4.

The factors of 384 are:

1 2 3 4 6 8 12 16 24 32 48 64 96 128 192 384

The factors of 100 are:

1 2 4 5 10 20 25 50 100

Conversion formula (equation):

3.84=3.841=3.84 × 1001 × 100=384100=384÷4100÷4=9625

Solution:

3.84 = 9625

What is a decimal?

A decimal is a numeral system that includes a point to separate the whole number part from the fractional part. This system makes it easy to work with numbers less than one.

What is a fraction?

A fraction is a mathematical way of showing a part of a whole. It has two parts: the numerator on top and the denominator below, which help express partial values and comparisons.

Step-by-step solution:

  • Step 1: First, write the decimal as a fraction over 1. This sets up the next steps. 3.84 = 3.841
  • Step 2: Decimals can have different lengths. We will align the number of digits after the decimal point. For 3.84, we have three digits. This means multiplying the fraction by a factor of 10 for each digit. Factor = 102 = 100
  • Step 3: Using this factor, multiply both the numerator and the denominator. 3.84 × 1001 × 100 = 384100
  • Step 4: Now we need to simplify the fraction by finding common divisors. The greatest common divisor is 4. Divide both the numerator and the denominator by this common divisor. 384 ÷ 4100 ÷ 4 = 9625
