4 liters of punch can serve 16.
5 liters of punch will be needed for 20 servings.
7 liters of punch will serve 28.
Step-by-step explanation:
Given,
Ratios of liters of punch to servings = 2:8
Let,
x be the servings for 4 liters.
New ratio of liters of punch to servings = 4:x
Using proportion;
Ratio :: New ratio

Product of mean = Product of extreme

Dividing both sides by 2

4 liters of punch can serve 16.
Let,
y be the liters of punch for 20 servings.
New ratio = y:20
Using proportion;

Product of mean = Product of extreme

Dividing both sides by 8

y=5
5 liters of punch will be needed for 20 servings.
Let,
z be the number of servings for 7 liters of punch.
New ratio = 7:z
Using proportion

Product of mean = Product of extreme

Dividing both sides by 2

7 liters of punch will serve 28.

Answer: There are 8 students at Hamilton Middle School with red hair.
Step-by-step explanation:
Given: The proportion of the students at Hamilton Middle School have red hair = 2% = 0.02
Total students in Hamilton Middle School = 400
Then , the number of students have red hair = (proportion of the students have red hair ) x (Total students )
= (0.02) x (400)
= 8
Hence, there are 8 students at Hamilton Middle School with red hair.
