In order to find the decimal form of each value, let's divide the numerator and denominator. In the case of a mixed number, we add the result to the integer part.
So we have:
[tex]\begin{gathered} \frac{39}{40}=0.975\\ \\ \\ \\ 7\frac{1}{2}=7+\frac{1}{2}=7+0.5=7.5\\ \\ \\ \\ 9\frac{7}{10}=9+\frac{7}{10}=9+0.7=9.7\\ \\ \\ \\ \frac{4}{5}=0.8 \end{gathered}[/tex]
