Question

I have 0.4 liters of seawater, and I give 22 students each a container and a 5milliter spoon. I ask them to put two spoonfuls into the container. How many milliliters of seawater will be left after all 22 students have filled their containers.

Answer 1

Answer: 180 milliliters

Explanation:

There are 22 students and they are to put two spoonfuls into the container.

Total spoonfuls is:

= 22 * 2

= 44 spoonfuls

Each spoonful is 5 milliliters:

= 5 * 44

= 220 milliliters in total.

1 litre = 1,000 milliliters

0.4 litres in milliliters is:

= 0.4 * 1,000

= 400 milliliters

Amount of water left in milliliters is:

= 400 - 220

= 180 milliliters
