We know the first place after decimal is tenths
The second place after decimal is hundredths
The third place after decimal is the thousandths place
So for 0.056
0 is at the tenths place
5 is at the hundredths place
and 6 is at the thousandths place
Expanding 22.056 we get
22.056 = 20 + 2 + 0.05 + 0.006
OR
22.056 = [tex]20+2+\frac{5}{100}+\frac{6}{1000}[/tex]
