Answer:
[tex]2\dfrac{1}{10}\ \text{acres}[/tex]
Step-by-step explanation:
[tex]9[/tex] acres of land split into [tex]4\dfrac{2}{7}[/tex].
Now
[tex]4\dfrac{2}{7}=4+\dfrac{2}{7}[/tex]
One section of land will be
[tex]\dfrac{9}{4+\dfrac{2}{7}}\\ =\dfrac{9}{\dfrac{30}{7}}\\ =\dfrac{63}{30}\\ =\dfrac{21}{10}=2\dfrac{1}{10}\ \text{acres}[/tex]
One section of the land is [tex]2\dfrac{1}{10}\ \text{acres}[/tex].
