Question

5/6+5/18-(3 7/9-2 13/15)

Answer 1

$\frac{5}{6} + \frac{5}{18} - (3 \frac{7}{9} - 2 \frac{13}{15} ) =0.2 \\ 1)3 \frac{7}{9} - 2 \frac{13}{15} = \frac{34}{9} - \frac{43}{15} = \frac{170 - 129}{45} = \frac{41}{45} \\ 2) \frac{5}{6} + \frac{5}{18} = \frac{15 + 5}{18} = \frac{20}{18} \\ 3) \frac{20}{18} - \frac{41}{45} = \frac{50 - 41}{45} = \frac{9}{45} = \frac{1}{5} = 0.2$
