Part 1: Simplifying Ratios

Express the following ratios in their simplest form:

12 : 18
25 : 75
48 : 32
60 : 90
100 : 25

Part 2: Identifying Equivalent Ratios

Determine if the following pairs of ratios are equivalent:

3 : 4 and 6 : 8
2 : 5 and 4 : 12
1 : 3 and 5 : 15
7 : 9 and 14 : 18
8 : 10 and 4 : 6

Part 3: Solving Proportions

Solve for the unknown variable in the following proportions:

x / 5 = 4 / 10
3 / y = 9 / 12
6 / 8 = z / 4
2 / 7 = 10 / a
b / 15 = 2 / 3

Part 4: Word Problems

Solve the following word problems using ratios and proportions:

A recipe calls for 2 cups of flour for every 3 cups of sugar. If you want to make a larger batch using 6 cups of flour, how many cups of sugar will you need?
A map has a scale of 1 inch = 50 miles. If two cities are 3.5 inches apart on the map, what is the actual distance between them?
A painter mixes 3 parts red paint with 2 parts blue paint to create a purple color. If he wants to make 10 gallons of purple paint, how many gallons of red paint will he need?
John earns $15 for every 2 hours he works. How much will he earn if he works for 8 hours?
A model car is built to a scale of 1:24. If the actual car is 12 feet long, how long is the model car in inches? (Remember 1 foot = 12 inches)

Answers to Ratio and Proportion Worksheet

Here are the answers to the worksheet questions. Review them carefully to understand where you might have made mistakes and to solidify your understanding of ratios and proportions.

Part 1: Simplifying Ratios
- 12 : 18 = 2 : 3
- 25 : 75 = 1 : 3
- 48 : 32 = 3 : 2
- 60 : 90 = 2 : 3
- 100 : 25 = 4 : 1
Part 2: Identifying Equivalent Ratios
- 3 : 4 and 6 : 8 = Equivalent
- 2 : 5 and 4 : 12 = Not Equivalent
- 1 : 3 and 5 : 15 = Equivalent
- 7 : 9 and 14 : 18 = Equivalent
- 8 : 10 and 4 : 6 = Not Equivalent
Part 3: Solving Proportions
- x / 5 = 4 / 10 => x = 2
- 3 / y = 9 / 12 => y = 4
- 6 / 8 = z / 4 => z = 3
- 2 / 7 = 10 / a => a = 35
- b / 15 = 2 / 3 => b = 10
Part 4: Word Problems
- 6 cups of flour will need 9 cups of sugar. (2/3 = 6/x => x = 9)
- The actual distance is 175 miles. (1/50 = 3.5/x => x = 175)
- He will need 6 gallons of red paint. (3/(3+2) = x/10 => x = 6)
- John will earn $60. (15/2 = x/8 => x = 60)
- The model car is 6 inches long. (1/24 = x/(12*12) => x = 6)

We hope this worksheet has helped you strengthen your understanding of ratios and proportions. Remember to practice regularly and apply these concepts to real-world situations to further solidify your knowledge. Keep learning, and keep exploring the fascinating world of mathematics!
