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

2:8::4:x

Product of mean = Product of extreme

8*4=2*x\\32=2x\\2x=32

Dividing both sides by 2

\frac{2x}{2}=\frac{32}{2}\\x=16

4 liters of punch can serve 16.

Let,

y be the liters of punch for 20 servings.

New ratio = y:20

Using proportion;

2:8::y:20

Product of mean = Product of extreme

8*y=20*2\\8y=40\\

Dividing both sides by 8

\frac{8y}{8}=\frac{40}{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

2:8::7:z\\

Product of mean = Product of extreme

8*7=2*z\\56=2z\\2z=56

Dividing both sides by 2

\frac{2z}{2}=\frac{56}{2}\\z=28

7 liters of punch will serve 28.

klio [65]

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.
