Question

Tolong dijawabkan nomor 13-15 (secepatnya)

Answer 1

13. 6 3/4 - 2 1/5 - 1 1/4=
6 15/20 - 2 4/20 - 1 5/20=
4 11/20 - 1 5/20 =
3 6/20 = 3 3/10 = 3,3
14. Diva : Ira : Reka = 4 : 9 : 17
Selisih Diva dan Ira = 9 - 4 = 5 ( 25 keping )
Diva = 4/5 × 25 keping = 20 keping
Ira = 9/5 × 25 keping = 45 keping
Reka = 17/5 × 25 keping = 85 keping
jumlah poin mereka = 20 keping + 45 keping + 85 keping = 150 keping
15. 1 + 1/2 + 1/4 + 1/8 =
8/8 + 4/8 + 2/8 + 1/8 =
15/8 = 1 7/8
