Question

Jerry is trying to round √11 to the nearest tenth.

To start, he looked for the perfect squares.

32 and 42

Jerry chose 42 to work with. What did he do wrong?

Answer 1

3^2 and 4^2

Answer 2

3^2 = 9
4^2 = 8
9 + 8 = 17

What does that have to do with the original problem?

Answer 3

Thats what im trying to figure out.

Answer 4

Well....
32 divided by 8 = 4

Answer 5

32 divided by 9 = 3.5 rounded to the nearest tenth = 4

Answer 6

42 divided by 8 = 5.25 so 5.3 (rounded to the nearest tenth)
42 divided by 9 = 4.6 so 4.7

Answer 7

That's the closest I can come to the answer. I'm not quite sure what to do next nor how that connects to the answer exactly. I hope I helped you out a little bit.
