Answer 1

Step-by-step explanation:

$\huge \frac{ \frac{1}{2} + \frac{2}{3} + \frac{1}{4} + \frac{3}{5} }{4} \\ = \huge \frac{( \frac{30 \times 1 + 20 \times 2 + 15 \times 1 + 12 \times 3}{60}) }{4} \\ = \huge \frac{ \frac{(30 + 40 + 30 + 36)}{60} }{4} \\ = \huge \frac{ \frac{(136)}{60} }{4} \\ = \huge \frac{136 \times 4}{60} \\ = \huge \frac{136}{15}$
