Understanding the decimal: “4.32”

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 4.32, 4 is the integer part and 32 is the fractional part.

Conversion Explanation:

For the numerator:
- We start with the number 4.32.
- By removing the decimal point, we derive the numerator as 432.
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.
Factors:
- The factors for the numerator and the denominator are numbers that can evenly divide each of them.
- For instance, the factors of 432 include 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 36, 48, 54, 72, 108, 144, 216, and 432.
- The factors of 100 comprise 1, 2, 4, 5, 10, 20, 25, 50, and 100.
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 432 and 100 is 4.

The factors of 432 are:

1 2 3 4 6 8 9 12 16 18 24 27 36 48 54 72 108 144 216 432

The factors of 100 are:

1 2 4 5 10 20 25 50 100

Conversion formula (equation):

$4.32 = \frac{4.32}{1} = \frac{4.32 × 100}{1 × 100} = \frac{432}{100} = \frac{432÷4}{100÷4} = \frac{108}{25}$

Solution:

4.32 = $\frac{108}{25}$

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. 4.32 = $\frac{4.32}{1}$
Step 2: Decimals can have different lengths. We will align the number of digits after the decimal point. For 4.32, 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. $\frac{4.32 × 100}{1 × 100}$ = $\frac{432}{100}$
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. $\frac{432 ÷ 4}{100 ÷ 4}$ = $\frac{108}{25}$

Answer in mixed fraction format:

4.32 =

4

8

25
