Răspuns:
x/3=14/6 = produsul mezilor(3,14) supra celalalt extrem(6) =>x=14×3/6
x=42/6
x=7
2/x=8/40
x= produsul extremilor(2,40) supra celalalt mez(8)
x=2×40/8
×=80/8
×=10
35/25=x/5
x=produsul mezilor(35,5) supra celalalt extrem (25)
x=35×5/25
×=175/25
x=calculezi tu
27/9=42/x
x=produsul extremilor supra celalalt mez
x=42×9/27
x=378/27
x= calculezi tu
5x/6=135/54
x= produsul mezilor supra produsul extremilor
x=5×54/6×135
x=faci tu mai deprade
