Fill 350 milliliter bottles from a 30 liter drum how many bottles
Mama L [17]

Answer:

  85

Step-by-step explanation:

0.350 L × n = 30 L . . . . . where n is the number of bottles.

Divide by 0.350:

  n = (30 L)/(0.350 L) ≈ 85.7

85 bottles can be filled, and one can be partially filled.

_____

Of course, you know the SI prefix milli- means 1/1000, so 350 mL = 350/1000 L = 0.350 L. When you do the division indicated above, ...

  (30 L)/(0.350 L)

the units of liters cancel, and you are left with the number of bottles.
