Jawaban:

1. a. – 25 : 5 = -5

b. 400 : (- 20): 10 = -2O :10 = -2

c. -600 : 20 : (-15) = -30: (-15) = 2

d.-1000 (-220) (-10) = 50:(-10) = -5

2. t = s/v = 40m/ 1m/jam = 40 jam

3. 60 : 5 = 12 buah

4. a. -12 x 8 + 72: (-6) = (-12 x8) + (72:(-6)) = -96+(-12) = -108

b. 80 : (-10) x 12- (-20) = -8 x 12 +20 = -96 + 20

= -76

c. 120 : 10 : (-6) + (-100) = 12 : (-6) – 100 = -2 – 100

= -102

d. 60 – (-20) x 12 + 75 = 60 + 240 +75 = 375

e. 200 : (-100) x 123 – (-125) = -2 x 123 + 125 = -246 + 125 = -121

5. (241 – 27 + 50) : 12 = 264 : 12 = 22

Jawaban:
