# How to calculate the ratio of two numbers?

#### Understand the Problem

The question is asking for a method to find the ratio between two quantities or numbers. The ratio is typically calculated by dividing one number by another, and it shows how much of one number exists in relation to the other.

Divide the first number by the second number and simplify if possible.

To calculate the ratio of two numbers, divide the first number by the second number and simplify if possible.

#### Steps to Solve

1. Identify the two numbers to compare

Clearly identify the two numbers for which you want to find the ratio. Let's denote these numbers as $a$ and $b$.

1. Divide the first number by the second number

Calculate the ratio by dividing the first number $a$ by the second number $b$.

$$\text{Ratio} = \frac{a}{b}$$

1. Simplify the ratio

If possible, simplify the fraction to its lowest terms. This can be done by finding the greatest common divisor (GCD) of both $a$ and $b$ and dividing both by that number.

1. Write the ratio in the desired format

The ratio can be expressed in different formats such as a fraction ($\frac{a}{b}$), with a colon ($a:b$), or as a decimal. Ensure to use the format required or preferred in your context.
