Answer:

Step-by-step explanation:

1. Find scale factor.

  • (because this is ratio, each value is multiplied by the same factor)

3x + 2x + x = 252

6x = 252

x = 42

2. Find number of males.

  • (the remainder make up females and teachers, combined)
  • 3x represents males...

3x = 3(42)

126 = # of males

3. Find percentage of males

  • percentage is a numerical representation out of 100 pertaining how much of a specific part is in a whole
  • there are 126 males out of the 252 attendees and teachers

126/252

= 0.5

= 50%
