Question

Gina started with 635 millilitres of liquid in a flask.

After pouring some some liquid out, the flask is pictured below.


How much liquid did Gina pour out of the flask?

Worked Solution

Since the flask now has 600 mL,

Volume of liquid poured out
= 635 −− 600
= 35 millilitres

Question

Timothy started with 53 millilitres of oil in a flask.

The picture below shows the flask after he poured some unused oil from a test tube back into it.


How much oil was poured back into the flask?

Worked Solution
Oil in the test tube = New volume − Original volume
= 80 −− 53
= 27 millilitres
