We can write tenths and hundredths as a common fraction or decimal fraction.
6 tenths can be written as (6 divided by 10)
[tex]\begin{gathered} fractional\: form=\frac{6}{10} \\ decimal\: form=0.6 \end{gathered}[/tex]Similarly, 20 hundredths can be written as (20 divided by 100)
[tex]\begin{gathered} fractional\: form=\frac{20}{100} \\ decimal\: form=0.20 \end{gathered}[/tex]4 units and 50 hundredths can be written as a mixed fraction (4 multiplied by 50 divided by 100)
[tex]\begin{gathered} mixed\: form=4\frac{50}{100} \\ fractional\: form=\frac{450}{100} \\ decimal\: form=4.50 \end{gathered}[/tex]
