Question

1 litre=1000cm³. About how many test tubes, each holding 24cm³ of water, can be filled from a

1 litre flask?

Answer 1

Answer: 125/3 or about 41.667

Note that you can't have 2/3 of a test tube, so the expected answer may be 42 test tubes.

Explanation:

Write a simple algebra equation using the word problem

24x = 1000

x represents the number of test-tubes, each of which hold 24cm^3 of water.

divide both sides by 24

x = 125/3 or about 41.667
