diketahui perbandingan
fika : siti = 3 : 4
fika : atik = 2 : 3
jumlah uang siti dan atik Rp 68.000
ditanya uang mereka masing2
jawab fika : siti : atik = (3x2) : (4x2) : (3x3) = 6 : 8 : 9
perbandingan untuk jumlah uang siti dan atik = 8 + 9 = 17
uang fika = 6/17 x 68000 = 24.000
uang siti = 8/17 x 68000 = 32.000
uang atik = 9/17 x 68000 = 36.000
semoga bermanfaat
