A map has a scale of 1 inch to 5 miles. If two towns are 8 inches apart on the map, how many miles apart are they in reality?
40 miles
50 miles
45 miles
35 miles
To find the real distance, multiply the map distance by the scale factor. Here, 8 inches × 5 miles per inch equals 40 miles. This uses a direct proportion between map inches and actual miles. More on solving proportions can be found at Math Is Fun.
A recipe calls for 2 cups of flour for every 3 cups of sugar. How much sugar is needed if you use 8 cups of flour?
10 cups
9 cups
11 cups
12 cups
Set up the proportion flour to sugar as 2:3 = 8:x. Solving gives x = (3/2)×8 = 12 cups of sugar. Proportions maintain equivalent ratios. Learn more at Khan Academy.
A car travels 180 miles on 6 gallons of gas. At the same rate, how many miles can it travel on 10 gallons?
300 miles
320 miles
280 miles
250 miles
First find miles per gallon: 180 miles ÷ 6 gallons = 30 mpg. Multiply by 10 gallons to get 300 miles. This shows a direct proportional relationship. More on rate problems at Math Is Fun.
In a class, the ratio of boys to girls is 3:4. If there are 12 boys, how many girls are there?
15 girls
16 girls
18 girls
14 girls
Set up 3:4 = 12:x. Solving x = (4/3)×12 = 16 girls. The ratio remains constant when scaled. See similar examples at Khan Academy.
A drink mix requires 2 parts juice for every 5 parts water. If you want to make 21 liters of the mix, how many liters of juice do you need?
6 liters
5 liters
7 liters
8 liters
Total parts = 2 + 5 = 7. Juice is 2/7 of the mix. Thus 2/7 × 21 = 6 liters of juice. Proportional division splits quantities by ratio. More on mixture problems at Math Is Fun.
If 5 pencils cost $3.00, how much do 8 pencils cost at the same rate?
$4.00
$3.60
$5.00
$4.80
Find cost per pencil: $3.00 ÷ 5 = $0.60 each. Multiply by 8 gives $4.80. Unit rate methods solve these proportional price questions. See examples at Khan Academy.
A car travels at a constant speed of 65 miles per hour. How far will it travel in 4.5 hours?
310 miles
300 miles
292.5 miles
280 miles
Distance = rate × time, so 65 mph × 4.5 hours = 292.5 miles. This formula is a direct proportion between distance and time. More on distance - time problems at Math Is Fun.
Tickets sold for a show are in the ratio of children to adults 7:5. If 96 tickets are sold in total, how many are children's tickets?
64 tickets
60 tickets
56 tickets
52 tickets
Total parts = 7 + 5 = 12. Children's share is 7/12 of 96, which equals 56. Proportionally dividing totals uses the same ratio principle. More at Khan Academy.
On a scale drawing, 3 cm represents 15 cm of the real object. How long will a 7 cm line on the drawing be in real life?
35 cm
28 cm
33 cm
30 cm
The scale factor is 15 ÷ 3 = 5. Multiply 7 by 5 to get 35 cm in real life. Scale drawings use proportional scaling between model and real sizes. Read more at Math Is Fun.
A town's population grew from 20,000 to 25,000 in 5 years at a constant rate. At the same rate, how many years will it take to grow from 20,000 to 35,000?
12 years
15 years
10 years
20 years
An increase of 5,000 in 5 years is 1,000 per year. To increase by 15,000 (to 35,000) at 1,000 per year takes 15 years. Constant growth problems use direct proportional reasoning. More at Khan Academy.
A punch recipe calls for 3 parts orange juice, 2 parts lemonade, and 5 parts water. If you need 50 liters of punch, how many liters of lemonade do you use?
10 liters
12 liters
15 liters
8 liters
Total parts = 3 + 2 + 5 = 10. Lemonade is 2/10 of the punch, so 2/10 × 50 = 10 liters. Mixture problems partition total by ratio. See more at Math Is Fun.
A model car is built to a scale of 1:18. If the real car is 4.2 meters long, how long is the model in centimeters?
20 cm
23.33 cm
24 cm
22 cm
Convert 4.2 m to 420 cm, then divide by 18: 420 ÷ 18 = 23.33 cm. Scale factors apply equally to all dimensions. More on scale models at Khan Academy.
You have a 6% acid solution and a 15% acid solution. How many liters of the 15% solution must you mix with the 6% solution to obtain 30 liters of a 10% solution?
10 liters
12 liters
13.33 liters
15 liters
Let x = liters of 15% solution. Then 15x + 6(30 - x) = 10×30. Solve 15x + 180 - 6x = 300, so 9x = 120 and x = 13.33 liters. Mixture equations equate total acid content. More at Math Is Fun.
Two similar triangles have corresponding side lengths in the ratio 5:8. If the smaller triangle's perimeter is 45 cm, what is the perimeter of the larger triangle?
68 cm
80 cm
72 cm
75 cm
Perimeters scale by the same factor as sides: 45 × (8/5) = 72 cm. Similar figures maintain proportional perimeters. Read more on similarity at Math Is Fun.

Cheat Sheet
Grasping Ratio Basics -
Learn that a ratio compares two quantities, such as 3:4 apples to oranges, and represents their relative sizes (source: NCTM). Visualizing ratios with diagrams or fraction notation (3/4) helps build a strong foundation for proportion word problems 7th grade. Practice translating "for every" statements into ratios to master 7th grade ratios.
Translating Word Problems into Proportions -
Convert a real-world scenario into a proportion by identifying equivalent ratios, for example "If 5 pencils cost $2, how much for 15?" becomes 5/2 = 15/x (source: Khan Academy). Underline key quantities and set up a ⎵/⎵ = ⎵/⎵ template before solving. This step-by-step process clarifies ratio and proportion questions every time.
Applying Cross-Multiplication -
Use cross-multiplication to solve proportions: if a/b = c/d, then a·d = b·c (source: University of Arizona Math Resources). For example, solve 5/2 = 15/x by computing 5·x = 2·15, so x = 30/5 = 6. This reliable method speeds up your math word problems 7th grade practice.
Using Unit Rates for Comparison -
Find a unit rate by dividing numerator by denominator (e.g., $2/5 pencils = $0.40 per pencil) to compare quantities quickly (source: Common Core State Standards). Unit rates simplify complex proportions and make 7th grade proportion practice feel like second nature. Remember the phrase "one at a time" to recall unit rate calculations.
Checking Your Answers with Inverse Operations -
After solving, plug your answer back into the original proportion to verify: cross-multiply again and confirm both products match (source: Stanford University Mathematics). This quick check builds confidence and prevents small mistakes from sneaking into your work. Embrace this habit for all ratio and proportion questions.
