Mrs.Smith teaches junior high school. During a class party in fourth period, she used 4/5 liters of soda for 12 students. If she had a class party in fifth period and used the same serving size, how many liters did she use for 30 students?

Answer:

Mrs. Smith used 2 liters of soda for 30 students.

Step-by-step explanation:

Given:

Number of students = 12

Amount of soda used for 12 students = 4/5 liters

We need to find amount of soda used for 30 students.

For 12 students = 4/5 liters of soda used

For 30 students = the amount of soda used

By Using Unitary Method we get

Amount of soda used = $\frac{4\times30}{5\times12}=\frac{120}{60} =2 \ litres$

Hence Mrs. Smith used 2 liters of soda for 30 students.
