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:

Step-by-step explanation:
anyone know the second one?
Answer:
d1= -d2+M
Step-by-step explanation:
you would multiply d1 and d2 by 1/2, then add negative d2/2 to each side, then divide each side by 2/1.
