Jawab:

Penjelasan dengan langkah-langkah:

1. (1/2 + 2/3) x 6/7 - 2/3 : 1/6

1/2 + 2/3 = 3/6 + 4/6 = 7/6.

7/6 x 6/7 = 1.

2/3 : 1/6 = 2/3 x 6 = 4.

1 - 4 = -3.

2. 8 + 3 x (-4) - 16 : 4

8 + (-12) - 4

8 - 12 - 4

-4 - 4

-8.

3. 5% + 6/4 x 2/3 - 12/5 : 10/15

6/4 x 2/3 = 1

12/5 : 10/15 = 12/5 x 15/10 = 36/10 = 3,6.

5% = 5/100 = 0,05.

0,05 + 1 - 3,6

1,05 - 3,6

-2,55.

Semoga membantu.
