Answer 2

We want to find the number of people who went canoeing or trekking so we add them up and subtract the 13

72+23-13= people who signed up for canoeing or trekking (an activity)

Answer 3

82

Answer 4

Right so be subtract that from the total amount because we want to find people who didn't sign up for anything

Answer 6

Right so thats the number of students, not a percentage
To find percentage divide it by the total amount

\(\%=\large \frac{part}{total}\)
