tolong Ya kak No 8-11 Sama caranya

8. (75 / 360) x 24 (diperkecil)
(5/24) x 24
5 jam

07.00 + 5 jam = 12.00 (c)

9. (30/360) x 24
(1/12) x 24
2 jam (a)

10. istirahat = (150/360) x 24
(10/24) x 24
10 jam
les = 2 jam
istirahat - les
= 10 jam - 2 jam
= 8 jam

11. 7 x 4 = 28 (total nilai 4 ulangan)
28 + 8 = 36 (total nilai 5 ulangan)
rata = 36 : 5
= 7,2
