Often, convert 36.25 to a fraction or 36.5 to a fraction, depending on the task.

Understanding the decimal: “36.4”

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 36.4, 36 is the integer part and 4 is the fractional part.

Conversion Explanation:

For the numerator:
- We start with the number 36.4.
- By removing the decimal point, we derive the numerator as 364.
For the denominator:
- Each position after the decimal represents a division by 10.
- Thus, having 1 positions after the decimal equates to 10 or 10¹.
Factors:
- The factors for the numerator and the denominator are numbers that can evenly divide each of them.
- For instance, the factors of 364 include 1, 2, 4, 7, 13, 14, 26, 28, 52, 91, 182, and 364.
- The factors of 10 comprise 1, 2, 5, and 10.
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 364 and 10 is 2.

The factors of 364 are:

1 2 4 7 13 14 26 28 52 91 182 364

The factors of 10 are:

1 2 5 10

Conversion formula (equation):

$36.4 = \frac{36.4}{1} = \frac{36.4 × 10}{1 × 10} = \frac{364}{10} = \frac{364÷2}{10÷2} = \frac{182}{5}$

Solution:

36.4 = $\frac{182}{5}$

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. 36.4 = $\frac{36.4}{1}$
Step 2: Decimals can have different lengths. We will align the number of digits after the decimal point. For 36.4, we have three digits. This means multiplying the fraction by a factor of 10 for each digit. Factor = 10¹ = 10
Step 3: Using this factor, multiply both the numerator and the denominator. $\frac{36.4 × 10}{1 × 10}$ = $\frac{364}{10}$
Step 4: Now we need to simplify the fraction by finding common divisors. The greatest common divisor is 2. Divide both the numerator and the denominator by this common divisor. $\frac{364 ÷ 2}{10 ÷ 2}$ = $\frac{182}{5}$
