Henry spent [tex]5\frac{1}{4}[/tex] hours on yard work.
Step-by-step explanation:
Given,
Time spent on cutting the grass = [tex]1\frac{1}{2}=\frac{3}{2}\ hours[/tex]
Time spent on pulling weeds = [tex]1\frac{3}{4}=\frac{7}{4}\ hours[/tex]
Time spent on sweeping and bagging = 2 hours
Total time spent = Time spent on cutting + Time spent on pulling + Time spent on sweeping
Total time spent = [tex]\frac{3}{2}+\frac{7}{4}+2[/tex]
Taking LCM
Total time spent = [tex]\frac{6+7+8}{4}=\frac{21}{4}[/tex]
Total time spent = [tex]5\frac{1}{4}[/tex] hours
Henry spent [tex]5\frac{1}{4}[/tex] hours on yard work.
