Clue 1

Fractions of a number

We found a secret note torn into scraps. If we count a fraction of the scraps, we can read the first clue!

Solve each problem to learn its letter. Then write that letter in every box that shows the same number, and read the secret clue.

2/10 of 75 =T

2/8 of 140 =A

2/6 of 63 =C

1/4 of 44 =H

8/10 of 10 =V

4/6 of 60 =O

5/10 of 68 =D

5/10 of 32 =I

4/8 of 64 =S

2/4 of 38 =E

1/8 of 200 =R

5/10 of 12 =L

2/4 of 74 =Y

1/3 of 69 =N

8/10 of 5 =P

0/15 letters found

Clue 2

Percentages

The spy walkie-talkie is running out of power. Solve this percentage puzzle to charge the battery and hear the next clue!

Solve each problem to learn its letter. Then write that letter in every box that shows the same number, and read the secret clue.

40% of 25 =T

5% of 260 =A

25% of 36 =K

40% of 95 =R

60% of 50 =N

5% of 20 =H

10% of 70 =P

Clue 4

Order of operations

We must press the colored buttons on the secret wall in the exact order of operations to open the clue box.

Solve each problem to learn its letter. Then write that letter in every box that shows the same number, and read the secret clue.

26 + 2 × 3 =A

1 + 2 × 4 =B

6 × 3 - 11 =P

38 + 6 × 3 =F

26 + 2 × 5 =N

30 + 8 × 3 =T

4 × 12 - 14 =M

3 × 12 - 23 =U

8 × 11 - 21 =C

34 + 9 × 2 =E

11 × 10 - 30 =H

4 × 11 - 24 =G

16 + 2 × 3 =I

4 + 7 × 7 =D

38 + 4 × 7 =R

8 × 11 - 30 =L

0/16 letters found

Clue 5

Fractions of a number — the last clue

We found a bag of shiny glass marbles. If we share a fraction of them with our team, we will find 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

6/8 of 8 = ?

1/8 of 32 = ?

1/3 of 3 = ?

5/10 of 22 = ?

1/10 of 90 = ?

2/8 of 8 = ?

2/3 of 15 = ?

1/4 of 20 = ?

1/10 of 80 = ?

3/6 of 24 = ?

2/4 of 6 = ?

Step 2 — cross out the sentence with each answer

1.The villain points to a royal blue badge, then looks through a pocket magnifier.

2.The villain flashes a shiny silver badge, then looks through a pocket magnifier.

3.The villain rubs a sparkly pink badge, then whispers into a toy walkie talkie.

4.The villain shows a bright gold badge, then snaps a photo with a spy camera.
