Agus : Budi = 6 : 5Budi : Anto = 5 : 7
Agus : Budi : Anto = 6 : 5 : 7
Diket jumlah Agus dan Anto = 65
Agus = 6/13 × 65 = 30 buku
Budi = 5/13 × 65 = 25 buku
Anto = 7/13 × 65 = 35 buku
Matematika SD Kelas VI
Agus = a
Budi = b
Anto = c
a : b = 6 : 5
b : c = 5 : 7
a : b : c = 6 : 5 : 7
a = (6/(6 + 7)) x 65
= (6/13) x 65
= 30 buku
b = (5/(6 + 7)) x 65
= (5/13) x 65
= 25 buku
c = (7/(6 + 7)) x 65
= (7/13) x 65
= 35 buku
Banyak buku yang dibaca Agus = 30 buku; Budi = 25 buku; Anto = 35 buku
