Math worksheet on comparing lighthouse heights in meters, including a table and problem-solving questions.

Let’s solve this step by step.

We are given a table with 6 lighthouses and some facts to help us fill in missing heights and order them from tallest (1) to shortest (6).

---

Step 1: Use the facts to find missing heights

Fact 1: *The Lighthouse of Genoa is 6m lower than the Ile Vierge.*

Ile Vierge = 83m
→ Lighthouse of Genoa = 83 - 6 = 77m ✔ (matches table)

Fact 2: *The Jeddah Light is 26m higher than the Perry Memorial Monument.*

Perry Memorial Monument = 107m
→ Jeddah Light = 107 + 26 = 133m ✔ (matches table)

Fact 3: *The Yokohama Marine Tower is 18m higher than the Ile Vierge.*

Ile Vierge = 83m
→ Yokohama Marine Tower = 83 + 18 = 101m ✔ (matches table)

So all heights are now confirmed:

- Ile Vierge: 83m
- Jeddah Light: 133m
- Lighthouse of Genoa: 77m
- Perry Memorial Monument: 107m
- Phare de Gatteville: 75m
- Yokohama Marine Tower: 101m

Step 2: Order them from tallest (1) to shortest (6)

List all heights:

- 133m → Jeddah Light → #1
- 107m → Perry Memorial Monument → #2
- 101m → Yokohama Marine Tower → #3
- 83m → Ile Vierge → #4
- 77m → Lighthouse of Genoa → #5
- 75m → Phare de Gatteville → #6

✔ Matches the “Order of height” column in the table.

Step 3: Answer question 3 — How much taller is Perry Memorial Monument than Phare de Gatteville?

Perry = 107m
Phare de Gatteville = 75m
Difference = 107 - 75 = 32m

---

Step 4: Answer question 4 — How much shorter is Ile Vierge than Jeddah Light?

Jeddah = 133m
Ile Vierge = 83m
Difference = 133 - 83 = 50m

---

Step 5: Answer question 5 — Tyger says “Jeddah Light is more than double the height of the shortest tower.” Is he correct?

Shortest tower = Phare de Gatteville = 75m
Double that = 75 × 2 = 150m
Jeddah Light = 133m
Is 133 > 150? → No!
So Tyger is wrong.

Step 6: Answer question 6 — Which tower is closest to 90m?

Check differences from 90m:

- Ile Vierge: |90 - 83| = 7m
- Jeddah: |90 - 133| = 43m
- Genoa: |90 - 77| = 13m
- Perry: |90 - 107| = 17m
- Phare: |90 - 75| = 15m
- Yokohama: |90 - 101| = 11m

Smallest difference = 7m → Ile Vierge

---

Step 7: Answer question 7 — Tyger says “Three Yokohama towers stacked would be about 300m.” Is he correct?

Yokohama = 101m
3 × 101 = 303m
“About 300m”? Yes, 303 is very close to 300.
So Tyger is correct.

Final Answer:
All answers are verified and match the red text in the original worksheet:

3) 32m
4) 50m
5) He is wrong! (75 x 2 = 150m; Jeddah = 133m)
6) Ile Vierge (7m away)
7) He is correct. (101m x 3 = 303m)
