Question

put these numbers in order from greatest to least.
0.643 0.0064 6.43 3.46

Explanation:

Step1: Compare integer parts

The integer parts of the numbers: \(0.643\) has \(0\), \(0.0064\) has \(0\), \(6.43\) has \(6\), \(3.46\) has \(3\). Since \(6 > 3 > 0\), \(6.43\) and \(3.46\) are greater than \(0.643\) and \(0.0064\). Among \(6.43\) and \(3.46\), \(6.43>3.46\) because \(6 > 3\).

Step2: Compare the two with 0 integer part

For \(0.643\) and \(0.0064\), compare the tenths place. \(0.643\) has \(6\) in tenths place, \(0.0064\) has \(0\) in tenths place. So \(0.643 > 0.0064\).

Step3: Combine the order

From greatest to least: \(6.43\), \(3.46\), \(0.643\), \(0.0064\).

Answer:

\(6.43\), \(3.46\), \(0.643\), \(0.0064\)
