Question

8/3+9/3-15/3
20/7-35/7+8/7
42/11-93/11+23/11-3/11

Answer 1

Respuesta:

$\frac{8}{3} + \frac{9}{ 3} - \frac{15}{ 3} = \frac{8 + 9 - 15}{3} = \frac{17 - 15}{3} = \frac{2}{3}$

$\frac{20}{7} - \frac{35}{7} + \frac{8}{7} = \frac{20 - 35 + 8}{7} = \frac{28 - 35}{7} = \frac{ - 7}{7} = - 1$

$\frac{42}{11} - \frac{93}{11} + \frac{23}{11} - \frac{3}{11} \\ = \frac{42 - 93 + 23 - 3}{11} = \frac{65 - 96}{11} = \frac{ - 31}{11}$
