Question

tolong bantuin jawab besok dikumpulin, mkasii​

Answer 1

1. 5 - 12 = -7

2. -7 - 11 = -18

3. -4 - 13 = -17

4. -5 + 9 = 4

5. 2/3 + 1/4 = 8/12 + 3/12 = 11/12 = 11/12

6. 3,5 - 7,2 = -3,7

7. -6 - 3 + 2 = -7

8. 3 - 12 + 6 - 2 = -5

9. -3/4 - 5/6 + 5/12 = -9/12 -10/12 + 5/12 = -14/12 = -7/6

Answer 2

Jawaban:

1. (+5) + (-12)

= 5 - 12

= -7

2. (-7) + (-11)

= (-7) -11

= -18

3. (-4) - (+13)

= (-4) - 13

= -17

4. (-5) - (-9)

= (-5) + 9

= 4

5.

[tex]( + \frac{2}{3} ) - ( - \frac{1}{4} ) \\ = \frac{2}{3} + \frac{1}{4} \\ = \frac{8 + 3}{12} \\ = \frac{11}{12} [/tex]

6. 3,5 - 7,2

= -3,7

7. -6 + (-3) - (-2)

= -6 - 3 + 2

= -7

8. 3 - 12 + 6 - 2

= -5

9.

[tex] - \frac{3}{4} + ( - \frac{5}{6} ) + \frac{5}{12} \\ = - \frac{3}{4} - \frac{5}{6} + \frac{5}{12} \\ = \frac{ - 9 - 10 + 5}{12} \\ = -\frac{14}{12} \\ = - \frac{7}{6} \\ = - 1 \frac{1}{6} [/tex]
