Answer:
[tex]7\frac{5}{7}\ laps[/tex]
Step-by-step explanation:
we know that
To find out how many laps they ran, divide the total distance by the distance of one lap
step 1
Convert the total distance from mixed number to an improper fraction
[tex]6\frac{3}{4}\ mi=\frac{6*4+3}{4}=\frac{27}{4}\ mi[/tex]
step 2
Find the number of laps
[tex]\frac{(27/4)}{(7/8)}=\frac{54}{7}\ laps[/tex]
step 3
Convert the number of laps to mixed number
[tex]\frac{54}{7}=\frac{49}{7}+\frac{5}{7}=7\frac{5}{7}\ laps[/tex]
