Question

quero comparar minha resposta, e se está correta 112/17-9/45+3/6+21

Answer 1

$\frac{9}{45} = \frac{1}{5}$    

$\frac{112}{17} - \frac{1}{5} = \frac{543}{85}$

$\frac{3}{6} = \frac{1}{2}$

$\frac{543}{85} + \frac{1}{2} = \frac{1171}{170}$

$\frac{1171}{170} + 21 = \frac{1171}{170} + \frac{21}{1}$

$\frac{1171}{170} + \frac{21}{1} = \frac{1171}{170} + \frac{3570}{170}$

$\frac{1171}{170} + \frac{3570}{170} = \frac{4741}{170}$

Answer 2

Resposta:

$\frac{4469}{170}$

Explicação passo-a-passo:

$\frac{112}{17} - \frac{9}{45} + \frac{3}{6} + 21 \\ \\ \frac{112}{17} - \frac{9}{45} + \frac{1}{2} + 21 \\ \\ \frac{1120 - 306 + 85 + 3570}{170} \\ \\ \frac{4469}{170}$
