#### Work Step by Step

Americans spend time on leisure, TV and sports = 5 hours 10 minutes
Time in minutes = 5 * 60 min + 10 min = 310 min
They spend time on working = 3 hours 30 minutes = 3 * 60 min + 30 min = 210 min
Americans spend time on leisure, TV, and sports compared to working = $\frac{310}{210}$ = $\frac{31}{21}$
