Clue 1
Fractions of a number
The academy computers hold a master list of spy recruits. We only need to check a specific fraction of these files to find our first big lead.

Clue 2
Multiplication facts (1-12)
The rogue agent fled through a grid of training rooms. By multiplying the rows of security sensors, we can pinpoint where they disabled the alarm.

Clue 3
Rounding
A motion detector picked up a faint signal, but the screen only shows rounded numbers. Rounding the reading helps us track their exact path.

Clue 5
Fractions of a number — the last clue
A torn piece of paper contains part of an encrypted security code. We must calculate a fraction of the total digits to unlock the remaining 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
3/4 of 12 = ?
4/5 of 5 = ?
2/6 of 33 = ?
4/10 of 20 = ?
1/2 of 24 = ?
1/5 of 25 = ?
1/4 of 28 = ?
2/6 of 3 = ?
1/4 of 8 = ?
5/8 of 16 = ?
3/10 of 10 = ?
Step 2 — cross out the sentence with each answer
1.The villain shined a laser pointer to blind the camera, then sent out a decoy drone to distract the dogs.
2.The villain dropped a smoke bomb to confuse the guards, then cracked the mainframe with a code breaker.
3.The villain activated jet shoes to zoom over the floor, then wiped the security logs with a memory eraser.
4.The villain shined a laser pointer to blind the camera, then wiped the security logs with a memory eraser.
5.The villain flipped on a night visor to see in the dark, then blocked communications using a signal jammer.
6.The villain activated jet shoes to zoom over the floor, then cracked the mainframe with a code breaker.
7.The villain activated jet shoes to zoom over the floor, then sent out a decoy drone to distract the dogs.
8.The villain fired a grappling hook to scale the balcony, then sent out a decoy drone to distract the dogs.
9.The villain flipped on a night visor to see in the dark, then cracked the mainframe with a code breaker.
10.The villain dropped a smoke bomb to confuse the guards, then sneaked past security with a logic bypass.
11.The villain flipped on a night visor to see in the dark, then sent out a decoy drone to distract the dogs.
12.The villain fired a grappling hook to scale the balcony, then blocked communications using a signal jammer.
