Question

5/9-(-1/2+5/6)+(-2/3+1)= calcular a expressão

Answer 1

Resposta:

0,55

Explicação passo-a-passo:

$\frac{5}{9} - ( - \frac{1}{2} + \frac{5}{6} ) + ( - \frac{2}{3} + 1) =$

$\frac{5}{9} + \frac{1}{2} - \frac{5}{6} - \frac{2}{3} + 1 =$

9, 2, 6, 3, 1 | 2

9, 1, 3, 3, 1 | 3

3, 1, 1, 1, 1 | 3

1, 1, 1, 1, 1 MMC 2×3×3=

MMC 6×3 =

MMC = 18

$\frac{10 + 9 - 15 - 12 + 18}{18} =$

$\frac{10 + 9 + 18 - 15 - 12}{18} =$

$\frac{37 - 27}{18} =$

$\frac{10( \div 2)}{18( \div 2)} =$

$\frac{5}{9} = 0.55$
