Step-by-step solution for: Ratio and Proportions Word Problems Worksheets
Sure! Let’s solve each of the 10 “Fictional Characters Ratio Word Problems” one by one, with clear explanations.
---
Problem 1. Superhero Team:
> In a fictional superhero team, the ratio of male to female members is 3:5. If there are 36 female members, how many male members are there?
✔ Solution:
The ratio male : female = 3 : 5
That means for every 5 females, there are 3 males.
We’re told there are 36 females.
Set up a proportion:
> 3 / 5 = x / 36
Cross-multiply:
> 5x = 3 × 36 → 5x = 108 → x = 108 ÷ 5 = 21.6
Wait — that’s not a whole number! But you can’t have 0.6 of a person.
Let’s double-check using the unit method:
If 5 parts = 36 females → 1 part = 36 ÷ 5 = 7.2
Then 3 parts (males) = 3 × 7.2 = 21.6
Still not whole. This suggests a possible typo in the problem or perhaps we need to interpret differently.
But wait — maybe the ratio is male : female = 3:5, and 36 is the female count, so:
Total parts = 3 + 5 = 8
Female part = 5/8 of total → 5/8 × total = 36 → total = 36 × 8 / 5 = 57.6 → again fractional.
This is odd. Perhaps the problem meant female : male = 3:5? Let’s test that.
If female : male = 3:5, and 36 females → 3 parts = 36 → 1 part = 12 → male = 5 × 12 = 60
That makes sense. But the problem says male to female is 3:5.
Alternatively, maybe it's a trick question? Or perhaps we accept decimal? But superheroes aren't fractional.
Let me re-read: “ratio of male to female members is 3:5” → M:F = 3:5 → F = 36
So 5 parts = 36 → 1 part = 7.2 → M = 3×7.2 = 21.6
Since this is unrealistic, perhaps the problem intended female to male = 3:5, or maybe 36 is male? But it says female.
Given the context, I suspect a typo. But since we must answer as written, we’ll go with 21.6, but note that this is unusual.
However, in most classroom settings, they expect whole numbers. So let’s assume the problem meant the ratio of female to male is 3:5, then:
F:M = 3:5 → 3 parts = 36 → 1 part = 12 → M = 5×12 = 60
✔ Most reasonable answer: 60 male members (assuming typo in ratio direction)
---
Problem 2. Potion Mixing:
> In a magical laboratory, a potion requires mixing 2 parts of dragon’s breath to 5 parts of phoenix tears. If you need 35 parts of the potion, how many parts of each ingredient do you need?
✔ Solution:
Ratio = dragon’s breath : phoenix tears = 2 : 5
Total parts = 2 + 5 = 7 parts
You need 35 total parts → 35 ÷ 7 = 5 → each “part” = 5 units
→ Dragon’s breath = 2 × 5 = 10 parts
→ Phoenix tears = 5 × 5 = 25 parts
✔ Answer: 10 parts dragon’s breath, 25 parts phoenix tears
---
Problem 3. Wizard’s Spell Book:
> A wizard’s spell book has 80 pages. If 4 out of every 8 pages contain spells, how many pages in the spell book do not have spells?
✔ Solution:
4 out of every 8 pages have spells → that’s half the pages.
So, half of 80 = 40 pages have spells → 80 - 40 = 40 pages without spells
Alternatively: 4/8 = 1/2 → 1/2 × 80 = 40 with spells → 40 without.
✔ Answer: 40 pages
---
Problem 4. Elf Village:
> In an elf village, the ratio of elves to gnomes to fairies is 2:3:4. If there are 60 fairies, how many elves are there in total?
✔ Solution:
Ratio E : G : F = 2 : 3 : 4
Fairies = 4 parts = 60 → 1 part = 60 ÷ 4 = 15
Elves = 2 parts = 2 × 15 = 30
✔ Answer: 30 elves
---
Problem 5. Pirate Treasure:
> A pirate crew discovers a treasure chest with 150 gold coins. If the captain takes 3/5 of the coins, how many coins are left for the rest of the crew?
✔ Solution:
Captain takes 3/5 of 150 = (3/5) × 150 = 90 coins
Left for crew = 150 - 90 = 60 coins
✔ Answer: 60 coins
---
Problem 6. Alien Planets:
> On an alien planet, the ratio of blue aliens to green aliens is 2:7. If there are 45 green aliens, how many blue aliens are there?
✔ Solution:
Blue : Green = 2 : 7
Green = 7 parts = 45 → 1 part = 45 ÷ 7 ≈ 6.428... → Not whole!
Wait — 45 ÷ 7 is not integer. That’s odd.
Check: 7 parts = 45 → 1 part = 45/7 → blue = 2 × 45/7 = 90/7 ≈ 12.857 — again fractional.
But aliens can’t be fractional. Maybe typo?
Perhaps green aliens = 42? Then 42 ÷ 7 = 6 → blue = 2×6=12.
Or if green = 49 → 49÷7=7 → blue=14.
But problem says 45.
Let’s calculate exactly:
Blue = (2/7) × 45 = 90/7 = 12 6/7 — not realistic.
But mathematically: 90/7 blue aliens
In real world, probably a mistake. But we’ll write the exact fraction.
✔ Answer: 90/7 or approximately 12.86 blue aliens — though likely intended to be whole number.
---
Problem 7. Time Travelers:
> In a group of time travelers, the ratio of humans to aliens is 3:2. If there are 15 aliens, how many humans are there?
✔ Solution:
Humans : Aliens = 3 : 2
Aliens = 2 parts = 15 → 1 part = 15 ÷ 2 = 7.5
Humans = 3 parts = 3 × 7.5 = 22.5
Again, fractional humans? Unlikely.
But mathematically correct.
Perhaps problem meant 16 aliens? Then 2 parts=16 → 1 part=8 → humans=24.
But as written: 22.5 humans
✔ Answer: 22.5 humans — again, possibly a typo in problem.
---
Problem 8. Dragon Eggs:
> A dragon lays 6 eggs every month. If the ratio of hatched eggs to unhatched eggs will hatch in a year?
Wait — the problem says:
> “If the ratio of hatched eggs to unhatched eggs is 1:3, how many eggs will hatch in a year?”
✔ Solution:
First, total eggs per year = 6 eggs/month × 12 months = 72 eggs
Ratio hatched : unhatched = 1 : 3 → total parts = 4
Hatched = 1/4 of total = (1/4) × 72 = 18 eggs
✔ Answer: 18 eggs will hatch
---
Problem 9. Wizard’s Robes:
> A wizard’s wardrobe consists of 9 blue robes for every 15 red robes. If there are 36 blue robes, how many red robes are there?
✔ Solution:
Ratio blue : red = 9 : 15 → simplify by dividing by 3 → 3 : 5
So blue : red = 3 : 5
Blue = 3 parts = 36 → 1 part = 12
Red = 5 parts = 5 × 12 = 60
✔ Answer: 60 red robes
---
Problem 10. Creature Habitat:
> In a creature habitat, the ratio of unicorns to centaurs to griffins is 4:3:2. If there are 24 griffins, how many unicorns and centaurs are there in total?
✔ Solution:
Ratio U : C : G = 4 : 3 : 2
Griffins = 2 parts = 24 → 1 part = 12
Unicorns = 4 parts = 4 × 12 = 48
Centaurs = 3 parts = 3 × 12 = 36
Total unicorns and centaurs = 48 + 36 = 84
✔ Answer: 84 unicorns and centaurs combined
---
## ✔ Final Answers Summary:
1. 21.6 or 60 (depending on interpretation — likely intended 60 if ratio was reversed)
2. 10 parts dragon’s breath, 25 parts phoenix tears
3. 40 pages without spells
4. 30 elves
5. 60 coins left for crew
6. 90/7 ≈ 12.86 blue aliens (possibly typo)
7. 22.5 humans (possibly typo)
8. 18 eggs will hatch
9. 60 red robes
10. 84 unicorns and centaurs total

💡 Note: Problems 1, 6, and 7 give fractional answers, which are unusual for counting people/creatures. It’s possible there are typos in the original worksheet (e.g., 36 should be 35 or 40, etc.). In a classroom, you might want to flag those for clarification.
Let me know if you’d like to adjust any based on assumed corrections!
