Hole A gets filled with 9 mugs of pebbles.
Hole B gets filled with 18 mugs of pebbles.
Hole C gets filled with 12 mugs of pebbles.



• Mark A, B, C on the right hole in the picture.
• Which is the biggest pothole? _____________
• If jugs are used, hole A gets filled with 5 jugs. How many jugs of pebbles are needed to fill hole B? ____________

Answer 1

•


• Pothole B is the biggest pothole.

• 9 mugs of pebbles fill the hole A whereas only 5 jugs are required to fill hole A.
$\Rightarrow$ Capacity of 9 mugs = Capacity of 5 jugs
So, if we have to fill hole B, then the number of mugs required = 18
= 2 $\times$ 9
So, number of jugs required to fill pothole B = 2 $\times$ 5
= 10
Thus, 10 jugs are required to fill hole B.
