Question 1101981: A science teacher needs 95 millimeters of vinegar for each student . There are 25 students in her science class. Vinegar comes in 1 litre bottles. How many bottles of vinegar dose the teacher need for her class?
Answer by KMST(5328)   (Show Source):
You can put this solution on YOUR website! NOTES:
1) It should be "95 millilitres" (British English) or "95 milliliters" (American)
2) The accepted abbreviations I use for litre/liter and millilitre/milliliter are L and mL with a capital L.
3) In a country with an adequate education system,
every fifth-grader should be able to answer that question.
Sadly, that is not true in many places,
and the situation is probably getting worse in many places.
(95 mL) X 25 = 2375 mL of vinegar is what the science teacher needs.
The prefix "milli" means  ,
so there are 1000 mL in 1 L.
If the teacher buys two 1 litre bottles, the teacher will have
2 X (1000 mL) = 2000 mL vinegar,
and that is not enough.
The teacher should buy  1-L bottles,
as that will give the teacher
3 X (1000 mL) = 3000 mL vinegar,
which is enough.
You could find the amount needed in litres/liters
by dividing 2375 mL by 1000 mL/L to get 2.375 L,
but the teacher can not buy 2.375 bottles,
so he/she/they must buy 3.
