Order the following numbers from least to greatest. √12, -.3, (12) , .7 , √3 7.

-.3, √3, .7, √12, (12)

To order the numbers from least to greatest, we compare their magnitudes.

1. First, let's find the square roots of 12 and 3:
√12 ≈ 3.4641
√3 ≈ 1.7321

2. Now, we have the following numbers:
-.3, 1.7321, 3, .7, 3.4641, 7

3. Ordering from least to greatest:
-.3, .7, 1.7321, 3, 3.4641, 7

So, the ordered sequence is: -.3, .7, √3, 3, √12, 7.
