Answer 1

3 33/60+2 28/60=5 61/60=6 1/60

Answer 2

$3 \frac{11}{20} + 2 \frac{14}{30} = \frac{3 \times 20 + 11}{20} + \frac{2 \times 30 + 14}{30} = \frac{71}{20} + \frac{74}{30} = \frac{71 \times 3}{20 \times 3} + \frac{7 \times 2}{30 \times 2} = \frac{213 + 148}{60} = \frac{361}{60} = 6 \frac{1}{60}$
