Mapel : Matematika

Misalkan

a = 10
b = 2
c = 5

Maka

(( -a ) ÷ b ) ÷ ( - c ) = ( a ÷ c ) ÷ b
(( -10 ) ÷ 2 ) ÷ ( - 5 ) = ( 10 ÷ 5 ) ÷ 2
( - 5 ) ÷ ( - 5 ) = 2 ÷ 2
1 = 1 { TERBUKTI }

————————————————————
Misalkan :
a = 5
b = 4
c = 3

( - 5) / 4 : ( - 3) = (5 / 3) : 4
- 5 / 4 × 1 / - 3 = 5 / 3 × 1 / 4
-5 / - 12 = 5 / 12
0,4166¯ = 0,4166¯ ( TERBUKTI )

Semoga membantu kak ^_^
