Question

6 sendo A = (-1/2)2+(2/5)-1eb=1/3-(-1)-2
então o valor de
a/bé igual a
​

Answer 1

Resposta: 9/10

Explicação passo-a-passo:

$A = (-\frac{1}{2} ).2 + \frac{2}{5} \\ A = -1 + \frac{2}{5}\\A = \frac{-3}{5}\\\\\\B = \frac{1}{3} -(-1) -2\\B = \frac{1}{3} +1 - 2\\B = \frac{1}{3} -1\\B = \frac{-2}{3}\\\\\frac{A}{B} = \frac{\frac{-3}{5}}{\frac{-2}{3}} = \frac{-3}{5}.\frac{3}{-2} = \frac{9}{10}$
