Answer 1

$\frac{1}{3} \times 5.8 + \frac{1}{3} \times 8.3 = \frac{1}{3} \times 5 \frac{8}{10} + \frac{1}{3} \times 8 \frac{3}{10} = \frac{1}{3} \times 5 \frac{4}{5} + \frac{1}{3} \times \frac{83}{10} = \frac{1}{3} \times \frac{29}{5} + \frac{83}{30} = \frac{29}{15} + \frac{83}{30} = \frac{58 + 83}{30} = \frac{141}{30} = \frac{47}{10} = 4.7$
