tolong dijawb beserta caranya

Perbandingan
Mangga : apel = 7:6
Apel : salak = 5÷2

Mangga : apel÷ Salak
_____7 ÷ 6.......................(×5) ( agar 30
________5 : 2............( ×6)

Cari kpk 6 dan 5 = 2x3x5= 30

Mangga : apel÷ Salak = 35 ÷30÷12
Berat salak
= [12 /( 35+30+12)] ×616
=( 12 / 77 ) ×616
= 12×8
=96 gram

Pebandingan

Mangga = m
apel = a
salak = s

m : a = 7 : 6
a :  s = 5 : 2

m : a : s = (7x5) :(5x6) : (6x2) = 35 : 30 : 12
Jumlah berat = 616 gram
jumlah perbandingan = 77
Berat salak = 12/77 x 616 gram =  96 gram
