$\frac{-59}{9}$, -6, 4.3, $\sqrt {20}$

Work Step by Step

Convert all the numbers into decimals to easily compare them. We know the fact that negative numbers are less than positive numbers. Convert negative numbers: $\frac{-59}{9}$$\approx$-6.55 -6.55 is less than -6 so -6.55 is the least then -6. $\sqrt 20\approx4.47$ 4.47 is greater than 4.3 because in the tenth place, 3 is less than 4. Thus, we have the order: 4.3, $\sqrt 20$. Combining these numbers together, we have $\frac{-59}{9}$, -6, 4.3, $\sqrt {20}$.
