1.72x15=tx(72+18)72x15=90t
12 = t
2.6x15=(6+4)xq
9=q
3.2x10=6t
10/3 bulan = t
100 hari = t
Persediaan = satu karung
Penghuni = 72 orang
Waktu habis = 15 hari
Bertambah = 18 orang
waktu habis
= (72×15)/(72+18)
= 1080/90
= 12 hari
2)
Banyak kelereng = sekantong
Banyak anak = 6 orang
Masing-masing mendapat = 15 kelereng
Tambahan anak = 4 orang
Masing-masing mendapat kelereng
= (6 × 15)/(6 + 4)
= 90/10
= 9 kelereng
3)
Waktu = 2 bulan
Banyak pekerja = 10 orang
Banyak pekerja yang tersedia = 6 orang
Waktu
= (2 × 10)/6
= 20/6
= 3 2/6
= 3 1/3 bulan
= 3 bulan (1/3 × 30) hari
= 3 bulan 10 hari
