Understanding Ratios and Proportions
What is a Ratio?
A ratio is a comparison between two quantities, indicating how many times one value contains or is contained within the other. Ratios can be expressed in several forms, including:
- Fraction (e.g., 1/2)
- Colon (e.g., 1:2)
- Words (e.g., "1 to 2")
For example, if there are 5 apples and 3 oranges, the ratio of apples to oranges can be expressed as 5:3.
What is a Proportion?
Proportion, on the other hand, is an equation that states that two ratios are equal. It is often represented in the form:
- a/b = c/d
Where "a" and "b" are the first ratio, and "c" and "d" are the second ratio. For instance, if we have the ratio of 1:2, we can say that 1/2 = 2/4, which illustrates that these two ratios are proportional.
The Importance of Maths Ratio and Proportion Worksheets
Worksheets play a crucial role in the learning process for several reasons:
1. Reinforcement of Concepts
