Answer 2

Answer:

2 13/33

Step by step explanation:

Given:

$0.2 \: bar + 0.3 \: bar + 0.4 \: bar + 0.9 \: bar + 0.39 \: bar$

Convert each number in rational

$0.2 \: bar = \frac{2}{9} \\ 0.3 \: bar = \frac{3}{9} \\ 0.4 \: bar = \frac{4}{9} \\ 0.9 \: bar = \frac{9}{9 } = 1 \\ 0.39 \: bar = \frac{39}{99} = \frac{3 \times 13}{3 \times 33} = \frac{13}{33}$

$Required \: sum \\ = \frac{2}{9} + \frac{3}{9} + \frac{4}{9} + 1 + \frac{13}{33} \\ = \frac{2 + 3 + 4}{9} + 1 + \frac{13}{33} \\ = \frac{9}{9} + 1 + \frac{13}{33} \\ = 1 + 1 + \frac{13}{33}$

$= 2 + \frac{13}{33} \\ = 2 \frac{13}{33}$

Hence, the answer is 2 13/33.
