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

Often, convert 3.02 to a fraction or 3.05 to a fraction, depending on the task.

Understanding the decimal: “3.025”

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 3.025, 3 is the integer part and 025 is the fractional part.

Conversion Explanation:

For the numerator:
- We start with the number 3.025.
- By removing the decimal point, we derive the numerator as 3025.
For the denominator:
- Each position after the decimal represents a division by 10.
- Thus, having 3 positions after the decimal equates to 1000 or 10³.
Factors:
- The factors for the numerator and the denominator are numbers that can evenly divide each of them.
- For instance, the factors of 3025 include 1, 5, 11, 25, 55, 121, 275, 605, and 3025.
- The factors of 1000 comprise 1, 2, 4, 5, 8, 10, 20, 25, 40, 50, 100, 125, 200, 250, 500, and 1000.
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 3025 and 1000 is 25.

The factors of 3025 are:

1 5 11 25 55 121 275 605 3025

The factors of 1000 are:

1 2 4 5 8 10 20 25 40 50 100 125 200 250 500 1000

Conversion formula (equation):

$3.025 = \frac{3.025}{1} = \frac{3.025 × 1000}{1 × 1000} = \frac{3025}{1000} = \frac{3025÷25}{1000÷25} = \frac{121}{40}$

Solution:

3.025 = $\frac{121}{40}$

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. 3.025 = $\frac{3.025}{1}$
Step 2: Decimals can have different lengths. We will align the number of digits after the decimal point. For 3.025, we have three digits. This means multiplying the fraction by a factor of 10 for each digit. Factor = 10³ = 1000
Step 3: Using this factor, multiply both the numerator and the denominator. $\frac{3.025 × 1000}{1 × 1000}$ = $\frac{3025}{1000}$
Step 4: Now we need to simplify the fraction by finding common divisors. The greatest common divisor is 25. Divide both the numerator and the denominator by this common divisor. $\frac{3025 ÷ 25}{1000 ÷ 25}$ = $\frac{121}{40}$

Answer in mixed fraction format:

3.025 =

3

1

40
