First we have to know is that every number raised to zero is equal to one and every number raised to 1 is the same number.
[tex]10^0=1[/tex][tex]10^1=1[/tex]
So we solve the fractions.
When we divide by 1 we have the same number
16)
[tex]\frac{890.1}{10^0}=\frac{890.1}{1}=890.1[/tex]
When we have numbers divided by 10 we run the decimal point to the left one position
20)
[tex]\frac{0.52}{10^1}=\frac{0.52}{10}=0.052[/tex]
24)
[tex]\frac{77}{10^1}=\frac{77}{10}=7.7[/tex]
