Penjelasan dengan langkah-langkah:

(1) 11 - 17 + 13

= - 6 + 13

= 7

(2) - 14 + 19 + 12 - 20

= 5 + (-8)

= 5 - 8

= - 3

(3) - 3, 1 - 5, 9

= - (3, 1 + 5, 9)

= - 9, 0

(4) - 0, 6 - (-1)

= - 0, 6 + 1

= 0, 4

(5)

[tex]( \frac{1}{6} ) -( \frac{3}{4} ) \\ = \frac{1 \times 2}{6 \times 2} - \frac{3 \times 3}{4 \times 3} \\ = \frac{2}{12} - \frac{9}{12} \\ = \frac{2 - 9}{12} \\ = \frac{ - 7}{12} \\ = - \frac{7}{12} [/tex]

(6)

[tex]( - \frac{2}{7} ) + (\frac{6}{7} ) - ( \frac{3}{7} ) \\ = \frac{ - 2 + 6 - 3}{7} \\ = \frac{1}{7} [/tex]

Semoga membantu ;)
