Answer:

Question 1:

Filling Potholes This is a small town near Kohima. There are some potholes in the road. Before the rains come, children want to fill the holes with pebbles. They bring pebbles in mugs of the same size. 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:

• 

• Pothole B is the biggest pothole.

• 9 mugs of pebbles fill the hole A whereas only 5 jugs are required to fill hole A.

⇒Capacity of 9 mugs = Capacity of 5 jugs So, if we have to fill hole B, then the number of mugs required = 18 = 2

×9 So, number of jugs required to fill pothole B = 2

×5 = 10 Thus, 10 jugs are required to fill hole B.
