The Pangaea Paddock Panic

A Rogue Dino-Shifter has locked the Chief Paleontologist inside the T-Rex paddock! The saboteur used experimental DNA to shape-shift and escape. We must crack the security codes to identify the shifter before the paddock fences shut down completely.

Clue 1

Fractions of a number

To unlock the fossil database, we need to analyze the fractional distribution of fossilized bones found in the dig site. Calculate the fraction of the total skeleton retrieved to reveal 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.

1/5 of 185 =T

5/10 of 62 =S

5/10 of 58 =N

1/3 of 69 =R

4/8 of 70 =M

5/10 of 14 =I

3/6 of 22 =O

1/3 of 99 =B

2/8 of 160 =E

1/8 of 120 =D

4/8 of 64 =L

2/3 of 42 =F

6/8 of 28 =A

2/3 of 24 =U

2/10 of 15 =H

0/15 letters found

Clue 2

Percentages

The paddock's backup battery is running low. We must determine the exact percentage of power remaining in the security grid before the emergency gates lock us out forever.

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

20% of 170 =T

25% of 180 =C

5% of 700 =I

25% of 80 =F

40% of 30 =L

25% of 132 =S

50% of 2 =B

5% of 480 =A

10% of 30 =U

20% of 200 =H

5% of 500 =D

5% of 620 =N

20% of 95 =R

50% of 54 =E

25% of 176 =P

20% of 210 =O

0/16 letters found

Clue 3

Exponents

The dino-shifter used a fast-growing prehistoric vine to block our path. The vine cells multiply exponentially. Calculate the growth rate to clear the trail and find 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.

Clue 4

Order of operations

The security terminal requires a multi-step override sequence. We have to solve the operations in the exact order of importance to bypass the lockout screen.

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

7 × 5 - 1 =A

6 + 9 × 2 =H

12 × 7 - 19 =I

5 × 6 - 21 =L

66 + 2 × 6 =W

10 × 5 - 19 =B

10 × 6 - 12 =C

6 × 10 - 21 =S

6 + 4 × 9 =N

6 × 9 - 18 =P

5 × 11 - 27 =G

7 × 10 - 14 =E

12 × 5 - 1 =R

3 × 4 - 6 =U

10 × 5 - 21 =D

3 + 2 × 6 =Y

0/16 letters found

Clue 5

Division facts (1-12) — the last clue

We have to split the remaining tracking darts equally among our rescue teams. Divide the supply cache to secure our final lead on the shifter.

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

2 ÷ 2 = ?

32 ÷ 8 = ?

60 ÷ 10 = ?

25 ÷ 5 = ?

90 ÷ 9 = ?

30 ÷ 10 = ?

63 ÷ 9 = ?

60 ÷ 5 = ?

88 ÷ 8 = ?

64 ÷ 8 = ?

4 ÷ 2 = ?

Step 2 — cross out the sentence with each answer

1.The villain blocked the access road in Stegosaurus Form, then escaped into the jungle using a Vine Grapple.

2.The villain smashed the security gate in Triceratops Form, then shattered the lab windows with a Sonic Roarer.

3.The villain stomped around in T-Rex Form, then shattered the lab windows with a Sonic Roarer.

4.The villain stomped around in T-Rex Form, then scorched the control panel with a Lava Blaster.

5.The villain smashed the security gate in Triceratops Form, then escaped into the jungle using a Vine Grapple.

6.The villain blocked the access road in Stegosaurus Form, then mucked up the paddock gates with a Tar Launcher.

7.The villain swooped over the canopy in Pterodactyl Form, then scorched the control panel with a Lava Blaster.

8.The villain swooped over the canopy in Pterodactyl Form, then deflected the security drones with an Amber Shield.

9.The villain dashed through the brush in Raptor Form, then shattered the lab windows with a Sonic Roarer.

10.The villain smashed the security gate in Triceratops Form, then scorched the control panel with a Lava Blaster.

11.The villain dashed through the brush in Raptor Form, then scorched the control panel with a Lava Blaster.

12.The villain swooped over the canopy in Pterodactyl Form, then escaped into the jungle using a Vine Grapple.
