Bab PerbandinganMatematika SD Kelas VI
t : b = 3 : 4 = 18 : 24
b : a = 6 : 5 = 24 : 20
t : b : a = 18 : 24 : 20 → dijumlahkan = 18 + 24 + 20 = 62
jumlah kelereng mereka = (62/(t + a)) x 57
= (62/(18 + 20)) x 57
= (62/38) x 57
= 93 kelereng
Verified answer
T : B...... = 3 : 4......B : A = .....6 : 5
T : B : A = 18 : 24 : 20 = 9 : 12 : 10
Kelereng T + A = 57 buah
Jumlah kelereng mereka bertiga
= (9+12+10)/(9+10) × 57
= (31/19) × 57
= 93
Jadi jumlah kelereng mereka bertiga adalah 93 buah
