Answer:
[tex]\frac{4}{7}[/tex]
Step-by-step explanation:
Length of the border Mariana wants to put across the top of a wall = [tex]6\frac{3}{4}[/tex] feet
= [tex]\frac{27}{4}[/tex] feet
If she has the length of the border = [tex]3\frac{6}{7}[/tex] feet
= [tex]\frac{27}{7}[/tex] feet
Therefore, fraction of the project can be completed = [tex]\frac{\frac{27}{7}}{\frac{27}{4} }[/tex]
= [tex]\frac{27}{7}\times \frac{4}{27}[/tex]
= [tex]\frac{4}{7}[/tex]
Fraction of the project can be completed = [tex]\frac{4}{7}[/tex]
