Word problems on Ratio involve comparing the relative sizes of two or more quantities that are related in some way. To solve a word problem involving ratios, you need to carefully analyze the information provided and use the ratio to establish a relationship between the two quantities.
For example:
If you have two sets of measurements, one for the length of a pencil and one for its width, you can compare their ratios to determine the relative sizes of the two objects.
Suppose you have two prices, one for a book and one for its cover, and you are asked to find the ratio of the prices.
If you are given the lengths of two similar shapes, you can find their ratio by comparing their measurements.
Key concepts to understand in word problems on ratios:
Ratio: A ratio compares two quantities in a specific order.
Equivalent ratios: Ratios that are equal to each other are called equivalent ratios.
Scale factor: The scale factor is a constant that relates the ratio of two quantities.
Proportional relationship: A proportional relationship is a relationship between two quantities where the ratio between them is constant.
Relative size: The relative size of two quantities is determined by their ratio.
Tips for solving word problems on ratios:
Carefully read the problem and identify the two quantities involved.
Use the ratio to establish a relationship between the two quantities.
Use the scale factor to find the equivalent ratio or proportional relationship.
Divide the two quantities by the scale factor to find the relative size.
Draw a diagram or create a visual representation to help you understand the relationship between the two quantities
