Question

How many litres of sanitizer would be required if each of the students In a class of 40 students receive a bottle of 75 ml ?

Answer 1

Answer:

3 Litres

Step-by-step explanation:

First of all, establish that 1 Litre = 1000ml

Now if each student get 75ml of sanitizer, 40 students would get (40 x 75)ml of sanitzer ,which = 3,000ml

But since the question says how many litres,we would convert 3000ml to litres,thats where  '1 Litre = 1000ml' comes in handy, if 1000ml = 1 litre then 3000ml = 3 litres.
