Tentukan yang benar dari soal di bawah ini A. 20×(-2) ×40 B. 50:(-5) : -10 C. (-2) ×(-8) =16 D. (-20) :(-4) : -5 E. (-30) :(-3) =10

Jawaban dan langkah–langkah:

Soal A

20 × (-2) × 40 =

-40 × 40 =

= –1600

Soal B

50 ÷ (-5) ÷ (-10) =

-10 ÷ (-10) =

= 1

Soal C

-2 × (-8) = 16

16 = 16

Soal D

-20 ÷ (-4) ÷ (-5) =

5 ÷ (-5) =

= –1

Soal E

-30 ÷ (-3) = 10

10 = 10

Semoga Membantu

Jawaban:

$sf : a. : boxed{ sf color{red}{ - 1.600}}$

$sf : b. : boxed{ sf color{red}{ 1}}$

$sf : c. : boxed{ sf color{red}{ 16}}$

$sf : d. : boxed{ sf color{red}{ - 1}}$

$sf : e. : boxed{ sf color{red}{10}}$

Penyelesaian:

A. 20 × (-2) × 40

= (20 × (-2)) × 40

= -40 × 40

= –1.600

=============================

B. 50 : (-5) : (-10)

= (50 : (-5)) : (-10)

= -10 : (-10)

= 1

=============================

C. (-2) × (-8)

= 2 × 8

= 16

=============================

D. (-20) : (-4) : (-5)

= (-20 : (-4)) : (-5)

= 5 : (-5)

= –1

=============================

E. (-30) : (-3)

= 30 : 3

= 10
