Clue 5

Division facts (1-12) — the last clue

To search the river bank safely, we must split our team of junior rangers into equal groups. Sharing the gear fairly gives us our final lead.

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

54 ÷ 9 = ?

120 ÷ 12 = ?

72 ÷ 9 = ?

96 ÷ 8 = ?

90 ÷ 10 = ?

20 ÷ 5 = ?

18 ÷ 9 = ?

36 ÷ 12 = ?

77 ÷ 7 = ?

Step 2 — cross out the sentence with each answer

1.The villain swings across the river using a grappling hook, then signals the getaway crew with a golden toucan.

2.The villain navigates the winding trails with a brass compass, then speeds past the mud traps with a spotted panther.

3.The villain distracts the camp guards with a vibrant slingshot, then escapes into the trees with a chattering monkey.
