A recipe calls for flour to sugar in a ratio of 2:1. If you have 4 cups of flour, how many cups of sugar do you need to maintain the same ratio?
2 cups
1 cup
4 cups
0.5 cup
The ratio flour to sugar is 2 to 1, so sugar is half the amount of flour. With 4 cups of flour, you divide by 2 to get 2 cups of sugar. Ratios scale linearly, so doubling the flour doubles the sugar amount by the same factor. PurpleMath: Ratios and Proportions
The ratio of students to teachers in a school is 15:1. If there are 30 teachers, how many students are there?
450
30
15
300
With a 15:1 student-to-teacher ratio, each teacher corresponds to 15 students. Multiplying 15 by 30 teachers gives 450 students. This is a direct application of ratio scaling. MathIsFun: Ratios and Proportions
On a map, 1 inch represents 50 miles. If two cities are 3.5 inches apart on the map, what is the actual distance between them?
175 miles
150 miles
200 miles
125 miles
A scale of 1 inch to 50 miles means you multiply inches by 50 to get miles. So 3.5 inches × 50 miles/inch = 175 miles. Scales are proportional relationships between map distance and real distance. PurpleMath: Understanding Scale
If 5 notebooks cost $12.50, how much would 8 notebooks cost at the same rate?
$20.00
$25.00
$10.00
$30.00
First find the unit price: $12.50 ÷ 5 = $2.50 per notebook. Multiply by 8 to get $20.00. Proportions allow you to scale costs linearly. MathIsFun: Unit Rates
A car travels 180 miles on 6 gallons of gasoline. How many gallons will it need to travel 450 miles at the same fuel efficiency?
15 gallons
20 gallons
18 gallons
10 gallons
The car’s fuel efficiency is 180 miles ÷ 6 gallons = 30 miles per gallon. To go 450 miles, divide 450 by 30 to get 15 gallons. Maintaining the same rate ensures linear scaling. PurpleMath: Rates and Unit Rates
A solution has an acid-to-water ratio of 3:7. If you have a total of 50 liters of the solution, how many liters of acid are present?
15 liters
21 liters
35 liters
30 liters
The ratio parts total 3 + 7 = 10. Acid is 3/10 of the total. Multiply 50 liters × (3/10) = 15 liters of acid. Ratios divide quantities into proportional parts. BYJU’S: Ratio and Proportion
Person A can complete a job in 6 days, and Person B can complete the same job in 9 days. How long will it take them to complete the job if they work together?
3.6 days
4 days
3.5 days
4.5 days
A’s rate is 1/6 of the job per day, B’s rate is 1/9 per day. Combined rate is 1/6 + 1/9 = 5/18 per day. Time = 1 ÷ (5/18) = 18/5 = 3.6 days. PurpleMath: Work Rate Problems
Two triangles are similar. The sides of the smaller triangle are 3, 4, and 5. If the side corresponding to 3 in the larger triangle is 6, what are the lengths of the other two sides?
6, 8, and 10
6, 12, and 15
9, 12, and 15
6, 4, and 5
Similarity means all sides scale by the same factor. The scale factor is 6/3 = 2. Multiply 4 and 5 by 2 to get 8 and 10. Similar triangles preserve proportionality of sides. MathIsFun: Similar Triangles
A pool-filling pipe can fill a pool in 8 hours, and a second pipe can fill the same pool in 6 hours. If the second pipe is opened 2 hours after the first pipe, how long will it take to fill the pool completely?
4.57 hours
5 hours
4 hours
6 hours
Let t be the total hours for the first pipe. Its rate is 1/8, the second’s is 1/6, active for (t?2) hours. Equation: t/8 + (t?2)/6 = 1 leads to t = 32/7 ? 4.57 hours. PurpleMath: Combined Work Rates
If \(\frac{x}{y} = \frac{x+y}{x-y}\), what is the ratio \(x:y\) (assuming x and y are positive)?
1 + ?2
?2 - 1
1 - ?2
-1 - ?2
Set r = x/y. Then r = (r+1)/(r?1). Cross-multiply to get r(r?1) = r+1 ? r² ?2r ?1 = 0. Solve to find r = 1 ± ?2. The positive solution is 1 + ?2. Math StackExchange: Proportion Equation

Cheat Sheet

  1. Foundations of Ratios -

    Ratio expresses the relative size of two quantities and can be written as a:b or the fraction a/b. Master equivalent ratios by multiplying or dividing both terms by the same number; for example, 2:3 equals 4:6 according to Khan Academy's clear guidelines. Use the mnemonic "Scale Up, Scale Down" to quickly recognize matching ratios in any proportion word problem quiz.

  2. Cross-Multiplication Technique -

    Cross-multiplication turns the proportion a/b = c/d into the simple equation ad = bc, making it faster to solve proportion equations practice. For instance, solving 5/x = 2/3 involves 5·3 = 2·x, so x = 15/2. This reliable method is endorsed by MIT OpenCourseWare for its consistency in ratio and proportion word problems.

  3. Translating Word Problems -

    Identify keywords like "per," "for every," or "out of" to set up your equation correctly when you solve proportion word problems. For example, if 4 notebooks cost $12, "for every" signals 4/12 = x/20 when finding cost for 20 notebooks. Practicing this translation step in your proportion problems practice test builds both speed and confidence.

  4. Unit Rates and Scaling -

    Computing unit rates - such as miles per hour or dollars per item - simplifies larger ratio challenges by reducing them to a single-unit comparison. If a car covers 150 miles in 3 hours, the unit rate is 50 mph, so in 6 hours you'll travel 300 miles. This approach, recommended by Purplemath, is vital for real-world proportion equations practice.

  5. Direct vs. Inverse Proportions -

    In direct proportions, y increases as x increases (y1/x1 = y2/x2), whereas in inverse proportions, y decreases as x increases (x1·y1 = x2·y2). For instance, doubling workers halves the time needed to complete a job. Recognizing which model applies in your proportion word problem quiz ensures accurate, confident solutions.
