1. Learning Outcomes
Compute volume of liquid from a situation expressed
in fraction.
Solve problems in real context involving computation
of volume of liquid.
2. Compute volume of liquid from a situation expressed in
fraction
* of = ×
EXAMPLE 1:
of 400 l = × 400 l
=
= 150 l
EXAMPLE 2 : *Convert the mixed number into
improper fraction
1 of 1.2 l = ________ ml
= × 1200 ml
=
= 1600 ml
NOTES:
Cancellation Method should be emphasized to find the answer
involving multiplication of fraction by the whole number.

Example: 3 × 140 ml = 3 × 35 ml
4 1
= 105 ml
3. Solve problem in real context involving computation of
volume of liquid
Example 1:
5
A pail can be filled by 2.4 l of water. of it is filled with water.
8
Calculate the volume of water needed to fill up the pail.
* Filled with water
List the
5
clues given of 2.4 l
8
Convert
fraction into

= 1.5 l
Get the answer
2.4 l
- 1.5 l
0.9 l
4. Solve problem in real context involving computation of
volume of liquid
Example 2:
2
30 ml of water is added to of 660 ml already in the jug. What is the
3
total volume of water in the jug now?
• Volume of water added = 30 ml
List the • Volume of water in the jug =
clues given 2
of 660 ml
3
2
× 660 ml
Convert 3
fraction of 1320
ml
= ________ ml
3
= ml
Find the total volume
of water
30 ml
Added = 30 m
+ 440 ml
Already filled = 440 ml
