Jika a = ( -11 + 5 ) ( -3 ) dan b = ( -2 ) (7+2),nilai a:b =... a.-2 b.-1 c.1 d.2

[tex] \frac{a}{b} = \frac{( - 11 + 5)( - 3)}{( - 2)(7 + 2)} \\ = \frac{( - 6)( - 3)}{( - 2)(9)} \\ = \frac{18}{ - 18} \\ = - 1[/tex]
semoga membantu

>>a= (-11+5)(-3)
33-15
18
>>b= (-2) (7+2)
-14-4
18

a:b = 18:18
= 1 (c)
