Menentukan hasil operasi hitung

a. (37 + 35) + 15 = 87

b. -42 + (12 + 19) = -11

c. (-28 + 45) + 25 = 42

d. -53 + (23 + 26) = -4

e. (83 + (-117)) + 17 = -17

f. (17 × 25) × (-4) = -1.700

g. -20 × (5 × 48) = -4.800

h. (158 × 125) × (-8) = -158.000

i. ((-24) × 4) × (-5) = 480

j. (-125) × (8 × (-13)) = 13.000

Penjelasan dengan langkah-langkah

Diketahui :

a. (37 + 35) + 15 =           f. (17 × 25) × (-4) =

b. -42 + (12 + 19) =          g. -20 × (5 × 48) =

c. (-28 + 45) + 25 =        h. (158 × 125) × (-8) =

d. -53 + (23 + 26) =        i. ((-24) × 4) × (-5) =

e. (83 + (-117)) + 17 =       j. (-125) × (8 × (-13)) =

Ditanya :

Menentukan hasil operasi hitung menggunakan sifat asosiatif.

Jawab :

Menggunakan sifat asosiatif

a. (37 + 35) + 15 = 37 + (35 + 15) = 37 + 50 = 87

b. -42 + (12 + 19) = (-42 + 12) + 19 = -30 + 19 = -11

c. (-28 + 45) + 25 = (-28) + (45 + 25) = (-28) + 70 = 42

d. -53 + (23 + 26) = (-53 + 23) + 26 = (-30) + 26 = -4

e. (83 + (-117)) + 17 = 83 + (-117 + 17) = 83 - 100 = -17

f. (17 × 25) × (-4) = 17 × (25 × (-4)) = 17 × (-100) = -1.700

g. -20 × (5 × 48) = (-20 × 5) × 48 = -100 × 48 = -4.800

h. (158 × 125) × (-8) = 158 × (125 × (-8)) = 158 × (-1.000) = -158.000

i. ((-24) × 4) × (-5) = -24 × (4 × (-5)) = -24 × (-20) = 480

j. (-125) × (8 × (-13)) = (-125 × 8) × (-13) = -1.000 × (-13) = 13.000
