Jungle Ratio Word Problems worksheet with illustrated monkey and 10 math exercises.

Let’s solve each problem one by one, step by step. We’ll use ratios and simple math to find the answers.

---

1. Jungle Explorer: Parrots to monkeys is 2:5. There are 36 monkeys. How many parrots?

Ratio means for every 5 monkeys, there are 2 parrots.

So if 5 parts = 36 monkeys → 1 part = 36 ÷ 5 = 7.2

Then parrots = 2 parts = 2 × 7.2 = 14.4

Wait — you can’t have 0.4 of a parrot! That doesn’t make sense in real life. But since this is a math problem, we’ll go with the number as calculated.

But let’s double-check: Maybe the ratio was meant to be scaled up?

Actually, 2:5 = ? : 36

Cross multiply: 5 × ? = 2 × 36 → 5x = 72 → x = 72 ÷ 5 = 14.4

Hmm… maybe it’s okay as a decimal for now. Or perhaps the problem expects us to round? But no instruction says that. Let’s keep it as 14.4 for now — but wait, maybe I made a mistake?

No — actually, in ratio problems like this, sometimes numbers don’t come out whole. But let’s check again:

If 5 units = 36 → 1 unit = 7.2 → 2 units = 14.4 → So yes, 14.4 parrots.

But that’s weird. Maybe the problem has a typo? Or maybe we’re supposed to leave it as a fraction?

72/5 = 14.4 → same thing.

We’ll go with 14.4, but note: in real life, you’d expect whole animals. For now, we’ll accept the math answer.

2. Vine Climbing: Vine is 21 meters. Monkey climbs 3 meters in 4 seconds. How long to climb entire vine?

First, how many 3-meter sections in 21 meters?

21 ÷ 3 = 7 sections

Each section takes 4 seconds → 7 × 4 = 28 seconds

✔ Easy!

---

3. Fruit Feast: 18 monkeys eat 126 bananas in 3 days. How many per monkey per day?

Total bananas = 126
Total monkey-days = 18 monkeys × 3 days = 54 monkey-days

Bananas per monkey per day = 126 ÷ 54

Simplify: divide numerator and denominator by 18 → 126÷18=7, 54÷18=3 → 7/3 ≈ 2.333...

Or as a mixed number: 2⅓ bananas per monkey per day

✔ Correct.

---

4. Butterfly Spotting: Spotted to total butterflies is 3:10. Total spotted = 60. How many total butterflies?

Ratio 3:10 means 3 parts spotted out of 10 total.

So 3 parts = 60 → 1 part = 60 ÷ 3 = 20

Total = 10 parts = 10 × 20 = 200 butterflies

✔ Makes sense.

---

5. River Crossing: 12 crocodiles take 15 minutes to cross. How many needed to cross in 10 minutes?

This is an inverse relationship — more crocodiles working together should take less time? Wait — does that make sense?

Actually, think: If 12 crocs take 15 min, then the “work” is fixed — crossing the river.

Assuming they all help equally, then:

Number of crocs × time = constant (like work)

So 12 × 15 = 180 “crocodile-minutes”

To do it in 10 minutes: number of crocs = 180 ÷ 10 = 18 crocodiles

✔ Yes — more crocs, less time. Inverse proportion.

---

6. Sloth Speed: Travels 6 meters in 3 minutes. How long to travel 24 meters at same speed?

Speed = distance/time = 6m / 3min = 2 meters per minute

Time for 24 meters = 24 ÷ 2 = 12 minutes

Alternatively: 24 is 4 times 6 → so time is 4 × 3 = 12 minutes

✔ Same answer.

---

7. Snake Encounter: Poisonous to non-poisonous snakes is 1:8. Non-poisonous = 63. How many poisonous?

Ratio 1:8 → for every 8 non-poisonous, 1 poisonous.

So 8 parts = 63 → 1 part = 63 ÷ 8 = 7.875

Poisonous = 1 part = 7.875

Again, not a whole snake — but mathematically correct.

Check: 1:8 = x:63 → 8x = 63 → x = 63/8 = 7.875

✔ Answer is 7.875

---

8. Monkey Jump: Jumps 4 meters per leap. Needs to reach top of 20-meter tree. How many leaps?

20 ÷ 4 = 5 leaps

✔ Simple division.

---

9. Waterfall Flow: Ratio of water flow from two waterfalls is 3:7. First waterfall = 18 liters/sec. What’s second?

Ratio 3:7 → first is 3 parts = 18 L/s → 1 part = 18 ÷ 3 = 6

Second = 7 parts = 7 × 6 = 42 liters per second

✔ Perfect.

---

10. Animal Population: Tigers : Lions : Leopards = 5:3:4. Tigers = 64. Find lions and leopards.

Tigers = 5 parts = 64 → 1 part = 64 ÷ 5 = 12.8

Lions = 3 parts = 3 × 12.8 = 38.4

Leopards = 4 parts = 4 × 12.8 = 51.2

Again, decimals — but mathematically correct based on given numbers.

Check: 5:3:4 → 64 : 38.4 : 51.2 → divide all by 12.8 → 5:3:4 ✔

---

Now, compiling final answers:

Note: Some answers are decimals because the given numbers don’t divide evenly. In real-world contexts, we might round or assume whole animals, but since the problem didn’t specify, we give exact mathematical results.

Final Answers:

1. 14.4 parrots
2. 28 seconds
3. 2⅓ bananas per monkey per day (or 7/3)
4. 200 butterflies
5. 18 crocodiles
6. 12 minutes
7. 7.875 poisonous snakes
8. 5 leaps
9. 42 liters per second
10. Lions: 38.4, Leopards: 51.2

But wait — let me recheck #1 and #7 and #10 — maybe the problem expects fractions instead of decimals?

For #1: 72/5 = 14.4 → same
#7: 63/8 = 7.875 → same
#10: 64/5 = 12.8 → 3×12.8=38.4, 4×12.8=51.2

All correct.

However, in some school settings, they may prefer fractions.

Let’s write them as fractions where possible:

1. 72/5 or 14 2/5
3. 7/3 or 2 1/3
7. 63/8 or 7 7/8
10. Lions: 192/5 or 38 2/5; Leopards: 256/5 or 51 1/5

But unless specified, decimals are acceptable.

Since the problem says “solve accurately”, and doesn’t specify format, we’ll present both decimal and fractional forms where helpful — but for Final Answer, we’ll use decimals as they’re direct calculations.

Actually, looking back — perhaps I should present exact values without rounding.

But in the context of word problems involving animals, maybe the numbers were meant to be whole? Let me check if I misread any.

Problem 1: “ratio of parrots to monkeys is 2:5. If there are 36 monkeys...”

36 divided by 5 is not integer — so either the problem has a typo, or we accept decimal.

Same for others.

I think we proceed with calculated values.

Final Answer:

1. 14.4
2. 28
3. 2.333... or 7/3
4. 200
5. 18
6. 12
7. 7.875
8. 5
9. 42
10. Lions: 38.4, Leopards: 51.2

But to be precise and clean, let's write them as:

1. \frac{72}{5} or 14.4
But since user likely wants numerical answers, and instructions say "accurate", we'll use decimals.

Actually, let me see — in problem 3, “how many bananas does each monkey eat per day?” — 126 ÷ (18×3) = 126 ÷ 54 = 7/3 ≈ 2.333 — but perhaps better as fraction.

Similarly, others.

To avoid confusion, I’ll present exact fractions where decimals repeat or are messy.

Revised Final Answers:

1. 72/5 (or 14.4)
2. 28
3. 7/3 (or 2 1/3)
4. 200
5. 18
6. 12
7. 63/8 (or 7.875)
8. 5
9. 42
10. Lions: 192/5 (38.4), Leopards: 256/5 (51.2)

But for simplicity in final answer box, and since the problem didn't specify, I'll use decimals rounded to three places if needed, but most are exact.

Actually, 72/5 = 14.4 exactly
63/8 = 7.875 exactly
192/5 = 38.4 exactly
256/5 = 51.2 exactly
7/3 = 2.333... repeating — so better as fraction.

In educational contexts, fractions are often preferred for exactness.

Let me decide:

For #3: 7/3 is exact, 2.333 is approximate.

Similarly, others are exact decimals.

So for consistency, I'll use fractions for non-terminating decimals, decimals for terminating.

But 7/3 is the only non-terminating here.

Others:

1. 14.4 = 144/10 = 72/5 — but 14.4 is fine
3. 7/3
7. 7.875 = 63/8 — but 7.875 is exact
10. 38.4 and 51.2 are exact

So only #3 needs fraction.

But to be safe, I'll present all as decimals except #3 as fraction.

Final decision:

Final Answer:

1. 14.4
2. 28
3. \frac{7}{3}
4. 200
5. 18
6. 12
7. 7.875
8. 5
9. 42
10. Lions: 38.4, Leopards: 51.2

Yes.

Now, writing Final Answer section.
