To put the given numbers in order from least to greatest, let's first convert them into decimal form, if necessary:
- \(12.42857142\) is already decimal.
- \(7.61577310\) is already decimal.
- \(-9.42477796\) is already decimal.
- \(5.142857\) is already in decimal.
Now, let's compare the values:
- \(12.42857142\)
- \(7.61577310\)
- \(-9.42477796\)
- \(5.142857\)
Now we know the approximate values of each:
- \(12.42857142\) is approximately \(12.43\)
- \(7.61577310\) is approximately \(7.62\)
- \(-9.42477796\) is approximately \(-9.42\)
- \(5.142857\) is approximately \(5.14\)
Now we order them from least to greatest:
- \(-9.42477796\)
- \(5.142857\)
- \(7.61577310\)
- \(12.42857142\)
Putting it all together, the order from least to greatest is:
\(-3\pi\), \(\frac{36}{7}\), \(-\sqrt{58}\), \(12 \frac{3}{7}\)
