Understanding Proportions
A proportion is a statement that two ratios are equal. It is often written in the form of an equation, where the ratios are set equal to each other. In this article, we will focus on solving proportions, specifically the proportion .
What is a Proportion?
A proportion is a mathematical statement that two ratios are equal. It is often written in the form of an equation, where the ratios are set equal to each other. For example, the proportion states that the ratio of to is equal to the ratio of to .
Why are Proportions Important?
Proportions are an essential concept in mathematics, particularly in algebra and geometry. They are used to solve problems involving ratios, proportions, and percentages. In real-life situations, proportions are used to compare quantities, such as the ratio of a car's speed to the distance traveled, or the ratio of a recipe's ingredients to the number of servings.
How to Solve a Proportion
To solve a proportion, we need to find the value of the variable (in this case, ) that makes the two ratios equal. Here are the steps to solve a proportion:
- Write the proportion as an equation: Write the proportion as an equation, with the ratios set equal to each other.
- Cross-multiply: Cross-multiply the two ratios, which means multiplying the numerator of the first ratio by the denominator of the second ratio, and vice versa.
- Solve for the variable: Solve for the variable (in this case, ) by dividing both sides of the equation by the coefficient of the variable.
Solving the Proportion
Now, let's apply these steps to solve the proportion .
Step 1: Write the proportion as an equation
Step 2: Cross-multiply
Step 3: Solve for the variable
