The Sparkbolt Expo Sabotage
During the grand finale of the Sparkbolt Robotics Expo, a mysterious Rogue Bot hacked the main mainframe, stole the experimental master microchip, and escaped into the server ducts. Detective, we must analyze the data logs to identify the culprit before they upload the code to the global network!

Clue 5
Fractions of a number — the last clue
We found a corrupted drive and must isolate a fraction of the megabytes to extract the final decrypted video frame.
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
1/6 of 12 = ?
4/10 of 30 = ?
2/5 of 10 = ?
2/6 of 18 = ?
1/2 of 22 = ?
1/4 of 28 = ?
3/5 of 5 = ?
1/5 of 50 = ?
2/8 of 36 = ?
1/6 of 48 = ?
2/4 of 10 = ?
Step 2 — cross out the sentence with each answer
1.The villain pulled the heavy titanium safe close, then swung up into the ceiling vents.
2.The villain sliced through the heavy steel beams, then disappeared instantly with a stealth cloak.
3.The villain sliced through the heavy steel beams, then fled the scene using hover jets.
4.The villain drilled a hole directly into the vault, then disappeared instantly with a stealth cloak.
5.The villain drilled a hole directly into the vault, then blasted out of the window with rocket boosters.
6.The villain pulled the heavy titanium safe close, then fled the scene using hover jets.
7.The villain fused the steel vault lock with a welder, then disappeared instantly with a stealth cloak.
8.The villain distracted the guards with a light show, then rolled away quickly on tread wheels.
9.The villain drilled a hole directly into the vault, then swung up into the ceiling vents.
10.The villain distracted the guards with a light show, then disappeared instantly with a stealth cloak.
11.The villain pulled the heavy titanium safe close, then disappeared instantly with a stealth cloak.
