Question

9 piles of bricks are being stored in a spot. If the beavers are short of 9 bricks to completely fill the spot, which of the following options correctly represents the number of bricks required in total to fill the spot? (1 pile = 10 bricks)

• A.
• B.
• C.
• D.

Answer 1

The correct option is C

Detailed step-by-step solution:
Piles of bricks being stored = 9
As 1 pile = 10 bricks, 9 piles will have 9 sets of 10 bricks = 9 Tens or 90 bricks
Number of bricks the beavers are short of = 9
Total number of bricks required to fill the spot: 90 + 9 = 9 Tens + 9 Ones = 99
We can represent 99 as shown below.
So, option B correctly represents the total number of bricks required to fill the spot.
