You can try other values to get more familiar with the conversion process.

Often, convert 4.125 to a fraction or 4.135 to a fraction, depending on the task.

Understanding the decimal: “4.13”

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 4.13, 4 is the integer part and 13 is the fractional part.

Conversion Explanation:

For the numerator:
- We start with the number 4.13.
- By removing the decimal point, we derive the numerator as 413.
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 413 include 1, 7, 59, and 413.
- 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 413 and 100 is 1.

The factors of 413 are:

1 7 59 413

The factors of 100 are:

1 2 4 5 10 20 25 50 100

Conversion formula (equation):

$4.13 = \frac{4.13}{1} = \frac{4.13 × 100}{1 × 100} = \frac{413}{100} = \frac{413÷1}{100÷1} = \frac{413}{100}$

Solution:

4.13 = $\frac{413}{100}$

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. 4.13 = $\frac{4.13}{1}$
Step 2: Decimals can have different lengths. We will align the number of digits after the decimal point. For 4.13, 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. $\frac{4.13 × 100}{1 × 100}$ = $\frac{413}{100}$
Step 4: Now we need to simplify the fraction by finding common divisors. The greatest common divisor is 1. Divide both the numerator and the denominator by this common divisor. $\frac{413 ÷ 1}{100 ÷ 1}$ = $\frac{413}{100}$

Answer in mixed fraction format:

4.13 =

4

13

100
