Part-to-whole ratios compare one part to the entire set. For example, 'In a class of 30 students, 12 are boys. What is the ratio of boys to the total number of students?'
The solution involves writing the ratio as 12:30, which can be simplified to 2:5.
Comparing Ratios
Comparing ratios involves determining if two ratios are equivalent. For example, 'Is the ratio 3:5 equivalent to the ratio 6:10?'
The solution involves simplifying both ratios to their simplest forms and comparing them. In this case, both ratios simplify to 3:5, so they are equivalent.
Strategies for Solving Ratio Word Problems
1. Identify the Type of Ratio: Determine if the problem involves a part-to-part, part-to-whole, or comparing ratios.
2. Write the Ratio: Express the ratio in the form 'a to b' or 'a:b.'
3. Simplify the Ratio: Reduce the ratio to its simplest form by dividing both numbers by their greatest common divisor (GCD).
4. Solve the Problem: Use the simplified ratio to find the solution to the problem.
Practice Problems
1. In a garden, there are 8 roses and 12 tulips. What is the ratio of roses to tulips?
2. In a basket of fruit, there are 15 apples and 25 oranges. What is the ratio of apples to the total number of fruits?
3. Is the ratio 4:6 equivalent to the ratio 8:12?
4. In a class of 25 students, 10 are girls. What is the ratio of girls to boys?
