Answer:
0.06 is 10 times as much as 0.006

let the number be x
as per the condition 0.06 is 10 times as much as x.
Solve for x:
10 times as much as x represents as 
Then;
......[1]
Division property of equality states that you divide the same number to both sides of an equation.
divide by 10 to both sides in equation [1];

Simplify:
x = 0.006
Therefore, 0.06 is 10 times as much as 0.006
The next numbers are 32 and -64 the pattern multiplies by -2
