Question

The number of blocks has 9 in the ones place. The number in the hundreds place is one more than the number in the tens place. Those two numbers equal 11. How many blocks are there?

Answer 1

Let's denote number in the tens place with x. Then the number in hundreds place is (x+1). We can make an equation:

x + x + 1 = 11

2 x = 10

x = 5

This number is 659

Answer 2

The answer is 659. 9 is I. The ones place, 6 + 5=11, and 6 is one more than 5.
