Question

ayuda porfavor no le entiendo nada sólo digan donde se deben poner los paréntesis porfavor

Answer 1

a) $\frac{2-3-2}{5+8-7-2} = \frac{(2-3)(-2)}{(5)(+8-7)-2} = \frac{(-1)(-2)}{(5)(1)-2} = \frac{2}{5-2} = \frac{2}{3}$

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

c) $\frac{2-3+2-5}{4-3+1-2} = \frac{(2-3)+(2-5)}{(4)(-3+1)-2}= \frac{(-1)+(-3)}{(-8-2)}= \frac{-4}{-10} = \frac{4}{10}$
