Clue 5
Division facts (1-12) — the last clue
The detective team shared out the glowing direction badges equally. Solve this division problem to get the final 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
35 ÷ 7 = ?
33 ÷ 3 = ?
49 ÷ 7 = ?
14 ÷ 7 = ?
42 ÷ 7 = ?
80 ÷ 8 = ?
80 ÷ 10 = ?
10 ÷ 10 = ?
48 ÷ 12 = ?
84 ÷ 7 = ?
21 ÷ 7 = ?
Step 2 — cross out the sentence with each answer
1.The villain blasted a directional line, then zoomed off in graph boots.
2.The villain shot a glowing vector ray, then steered north with compass.
3.The villain fired an angle power blast, then drew a line with line tracer.
4.The villain fired an angle power blast, then zoomed off in graph boots.
5.The villain shot a glowing vector ray, then escaped with speed jetpack.
6.The villain dashed across the grid map, then blocked path with force shield.
7.The villain aimed a sharp arrow beam, then zoomed off in graph boots.
8.The villain shot a glowing vector ray, then zoomed off in graph boots.
9.The villain dashed across the grid map, then drew a line with line tracer.
10.The villain blasted a directional line, then blocked path with force shield.
11.The villain blasted a directional line, then escaped with speed jetpack.
12.The villain blasted a directional line, then steered north with compass.
