15t = 180
Divide both sides by 15
t = 12

Hence, the multiplication sentence is:

Solving (b): Rectangular fraction model
In (a) above, the result is 2/5
The fraction model will be represented as thus:
- Draw a rectangle
- Partition in to 5 equal parts (5 represents the denominator)
- Shade 2 of the 5 partitions (2 represents the numerator)
<em>See attachment for model</em>
0 if you add the thickness to the underside of the tank
No,
3/4 * 5=3.75
