Clue 5

Division facts (1-12) — the last clue

We have a pile of shiny tracking seeds to share equally among our team. Divide them up so we can search every path!

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

48 ÷ 6 = ?

10 ÷ 2 = ?

6 ÷ 6 = ?

42 ÷ 6 = ?

84 ÷ 7 = ?

11 ÷ 1 = ?

110 ÷ 11 = ?

16 ÷ 8 = ?

45 ÷ 5 = ?

12 ÷ 4 = ?

4 ÷ 1 = ?

Step 2 — cross out the sentence with each answer

1.The villain slides down a vine zipline, then reads the stolen map decoder.

2.The villain zooms off using jetpack boots, then reads the stolen map decoder.

3.The villain sails away on a wind glider, then swings away on a grappling hook.

4.The villain zooms off using jetpack boots, then swings away on a grappling hook.

5.The villain flies up with a propeller hat, then checks their glowing compass.

6.The villain sails away on a wind glider, then checks their glowing compass.

7.The villain zooms off using jetpack boots, then tosses noisy smoke bombs.

8.The villain flies up with a propeller hat, then reads the stolen map decoder.

9.The villain flies up with a propeller hat, then tosses noisy smoke bombs.

10.The villain leaps away with bounce shoes, then peers through spy binoculars.

11.The villain slides down a vine zipline, then checks their glowing compass.
