Clue 1

Fractions of a number

We analyzed the VIP guest list at the stadium. Only a fraction of the fans had access to the mixing board during the song launch, which points us to our first suspect filter.

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 5

Fractions of a number — the last clue

A fraction of the stadium speakers were blown out by the villain's bass drop. Calculating that exact fraction led us to the suspect's final hair 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
1/5 of 35 = ?
1/3 of 9 = ?

1/2 of 16 = ?
6/10 of 15 = ?
5/8 of 16 = ?
1/10 of 40 = ?
3/5 of 20 = ?
Step 2 — cross out the sentence with each answer
