Question

Select the number represented using flats, rods, and blocks.

Answer 1

Detailed step-by-step solution:
One flat represents 100.
One rod represents 10.
One block represents 1.

4 flats represent 100 + 100 + 100 + 100 = 400
3 rods represent 10 + 10 + 10 = 30
2 blocks represent 1 + 1 = 2

So, the number is:

H T O
4 0 0
3 0

4 3 2

Hence, option C is the correct answer.
