Ratio Concept

A ratio is a comparison of two or more numbers that indicates their relative sizes. Ratios can be expressed in different ways, such as using a colon (4:6), as a fraction (4/6), or using the word "to" (4 to 6). Ratios are used to compare quantities and can be simplified to their lowest terms.

Ratio Formula:
Ratio = First Number : Second Number
Steps

Calculation Methods

Here are the steps to calculate and simplify a ratio:

  1. 1
    Write the ratio using the given numbers
  2. 2
    Find the greatest common divisor (GCD) of both numbers
  3. 3
    Divide both numbers by the GCD to get the simplified ratio

For example, to simplify the ratio 4:6:

Example Calculation:
GCD of 4 and 6 is 2
4 ÷ 2 = 2
6 ÷ 2 = 3
Simplified ratio = 2:3
