The value 30 hundredths means:
[tex]\frac{30}{100}=\frac{3}{10}=0.3[/tex]
So color 30 of the small boxes in the box shown below as follows:
The first box represents ones, the second represents tenths and the third represents hundredths.
So 0.30 will be represented as no color, 30 colored and no colored again.
