Solution
The world population increases by 1.05℅ each year:
Per year = 1.05 %
1. number of months in a year = 12
[tex]months=\frac{1.05}{12}=0.0875\text{ \%}[/tex]
2. number of days in a year = 365
[tex]days=\frac{1.05}{365}=0.0029\text{ \%}[/tex]3. number of hours in a year = 8760
[tex]hours=\frac{1.05}{8760}=0.0001198\text{ \%}[/tex]
