A tank has a capacity of 230 L and is filled with water. How much water will be filled in 12 such tanks?
If a bucket has a capacity of 15 L, how many buckets can be filled with all the water? [4 marks]

Solution:
Capacity of the tank = 230 L
Amount of water in 12 tanks = 230 $\times$ 12

23
$\times$ $\underset{–}{12}$
46
$\underset{–}{230}$
276
Total amount of water = 276 $\times$ 10 = 2760 L [2 marks]

Capacity of a bucket = 15 L
So to find the number of buckets that can be filled, we need to divide 2760 by 15.

$$\begin{array}{c}184\\ 152760\\ -\underset{–}{15}2\\ 126\\ -\underset{–}{120}\\ 60\\ -\underset{–}{60}\\ 0\end{array}$$Thus, 2760 ÷ 15 = 184.
Thus, 184 buckets could be filled. [2 marks]
