Answer: 5: A fallen object was not the cause of injury.
Step-by-step explanation:
Convert [tex]3\frac{4}{7}[/tex] to an improper fraction:
[tex]3\frac{4}{7} =\frac{3*7+4}{7}[/tex]=[tex]\frac{21+4}{7}[/tex]=[tex]\frac{25}{7}[/tex]
Now, divide [tex]\frac{25}{7}[/tex] by [tex]\frac{5}{7}[/tex]:
[tex](\frac{25}{7} )/(\frac{5}{7} )[/tex]=[tex](\frac{25}{7} )(\frac{7}{5} )[/tex]=5
