Answer: To place √31 on the number line, we first need to find its approximate value.
√31 is between 5 and 6 since 5²=25 and 6²=36. To find a more precise value, we can use a calculator or estimate using long division.
Using a calculator, we get:
√31 ≈ 5.56776436
Rounding to tenths, we get:
√31 ≈ 5.6
To place 5.6 on the number line, we can mark the point between 5.5 and 5.7.
Here's a rough sketch of what it might look like:
0 1 2 3 4 5 6 7 8 9
