Clue 5

Division facts (1-12) — the last clue

The oil cans must be shared equally among the small helper bots. Each bot gets the same amount. Solve this division puzzle for the last clue.

First solve each problem. Then find each answer in the list below and cross that sentence out. One sentence will be left — that's exactly what the villain did!

Step 1 — solve these

24 ÷ 8 = ?

110 ÷ 10 = ?

8 ÷ 4 = ?

10 ÷ 10 = ?

108 ÷ 9 = ?

36 ÷ 6 = ?

8 ÷ 1 = ?

7 ÷ 1 = ?

28 ÷ 7 = ?

72 ÷ 8 = ?

110 ÷ 11 = ?

Step 2 — cross out the sentence with each answer

1.The villain blasts a laser beam, then flashes a holo screen.

2.The villain flies with a jet boost, then shines night vision.

3.The villain jumps with a super spring, then flashes a holo screen.

4.The villain uses a metal magnet, then flashes a holo screen.

5.The villain jumps with a super spring, then throws a spark punch.

6.The villain blasts a laser beam, then shines night vision.

7.The villain flies with a jet boost, then flashes a holo screen.

8.The villain blasts a laser beam, then makes a sonic beep.

9.The villain zooms on turbo wheels, then unfolds a solar panel.

10.The villain uses a metal magnet, then makes a sonic beep.

Answer Key — The Great Bolt City Chase

Culprit: Clank (super spring · spark punch · left gear spin · star top · salt water)

Clue 1 (Multiplication facts (1-12)): "THE ROBOT DOES NOT USE A SOLAR PANEL"
9 × 9 = 81 (T) · 2 × 1 = 2 (L) · 1 × 11 = 11 (B) · 5 × 6 = 30 (R) · 9 × 5 = 45 (P) · 4 × 4 = 16 (U) · 5 × 2 = 10 (A) · 3 × 11 = 33 (S) · 8 × 4 = 32 (O) · 8 × 11 = 88 (H) · 9 × 1 = 9 (N) · 3 × 1 = 3 (E) · 12 × 8 = 96 (D)
Clue 2 (Percentages): "THE BOT SPINS LEFT"
50% of 16 = 8 (T) · 5% of 580 = 29 (F) · 40% of 10 = 4 (N) · 50% of 36 = 18 (H) · 40% of 5 = 2 (O) · 5% of 20 = 1 (E) · 20% of 65 = 13 (P) · 10% of 30 = 3 (B) · 40% of 35 = 14 (L) · 20% of 160 = 32 (I) · 25% of 124 = 31 (S)
Clue 3 (Exponents): "SALT WATER WILL STOP THE BOT"
11^2 = 121 (S) · 8^2 = 64 (W) · 6^2 = 36 (R) · 2^3 = 8 (B) · 13^2 = 169 (E) · 12^2 = 144 (P) · 10^2 = 100 (A) · 7^2 = 49 (I) · 6^3 = 216 (L) · 3^2 = 9 (T) · 2^4 = 16 (H) · 3^3 = 27 (O)
Clue 4 (Order of operations): "THE BOT HAS A STAR ANTENNA"
35 + 5 × 2 = 45 (T) · 10 + 8 × 3 = 34 (S) · 9 × 10 - 29 = 61 (R) · 16 + 8 × 4 = 48 (N) · 8 × 12 - 23 = 73 (B) · 5 × 12 - 11 = 49 (A) · 2 + 2 × 3 = 8 (E) · 9 × 8 - 19 = 53 (H) · 4 + 3 × 2 = 10 (O)
Clue 5 (Division facts (1-12)): surviving statement (box 5) → Clank
24 ÷ 8 = 3 · 110 ÷ 10 = 11 · 8 ÷ 4 = 2 · 10 ÷ 10 = 1 · 108 ÷ 9 = 12 · 36 ÷ 6 = 6 · 8 ÷ 1 = 8 · 7 ÷ 1 = 7 · 28 ÷ 7 = 4 · 72 ÷ 8 = 9 · 110 ÷ 11 = 10
