Good 'ol ratio and proportion
so what yo do is
known ratio=unknown ratio
so first one
oranges
number of oranges to cost=5:2
find the cost of 2 dozen (24) oranges
number of oranges to cost=5:2
5:2=24:?
5/2=24/?
times both sides by 2 times ?
5 times ?=48
divide both sides by 5
?=9.6
2 dozen oranges costs $9.60
this one I can't see how many days
but for x days, the cost is x times $60

Answer:
(0,3)
Step-by-step explanation:
The question is incomplete. The complete question is :
Justin drinks 1 litter of water during the soccer practice. He drank 2,000 milliliters of water at his game. How many liters of water did he drink during his game and his practice? Explain.
Solution :
It is given that :
During practice, Justine drank = 1 liter of water
During game, Justine drank = 2000 milliliters of water
We know that,
1 liter = 1000 mL
Therefore, during the game, Justine drank :
1000 mL = 1 liter
∴ 2000 mL = 2 liter
So Justine drank 2 liters of water during his soccer game and 1 liter of water during his practice.
