Clue 5

Division facts (1-12) — the last clue

We need to share the block cleanup duties evenly among the online mods. Divide the dirty slime blocks among us to see if the Griefer used a left or right hand.

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

14 ÷ 2 = ?

108 ÷ 12 = ?

12 ÷ 4 = ?

66 ÷ 11 = ?

40 ÷ 8 = ?

96 ÷ 12 = ?

60 ÷ 5 = ?

20 ÷ 10 = ?

33 ÷ 3 = ?

110 ÷ 11 = ?

7 ÷ 7 = ?

Step 2 — cross out the sentence with each answer

1.The villain slashed the defensive banners, then boosted into the sky with fireworks.

2.The villain shot down the redstone lamps, then teleported away using ender pearls.

3.The villain dug a massive pit under the gate, then glided off into the dark night.
