Answer:
If there are 10 students taking only chemistry, 9 students taking only physics, and 5 students only taking both chemisty and 16 students are taking neither; I would add 10+9+5+16=40 (total students) and divide 10/40 (25% chemistry) 9/40 (22.5% physics) 5/40 (12.5% both) 16/40 (40% neither)
Step-by-step explanation:
1. Determine a single event with a single outcome.
2. Identify the total number of outcomes that can occur.
3. Divide the number of events by the number of possible outcomes.

#1---> let the number you are trying to find be x for the following questions
30%*x=15
x=15/30%
x=50
#2
10%*x=14
x=14/10%
x=140
#3
(4/32)*100
is the same as (1/8)*100= 12.5%
#4
1%* x=11
x=11/1%
x=1100
by the way * means multiply
5x + 13 Hope this helps you
