500kg -25/25
x - 1/25 =(500kg*1/25)/1=20kg
Sposób 1:
500 / 25 = 20
1/25 = 20 kg
Miedź - 22/25
22 * 20 = 440 kg
Cyna - 2/25
2 * 20 - 40 kg
Cynk - 500 - (440 + 40) = 500 - 480 = 20 kg
Sposób 2:
25/25 = miedź + cyna + cynk
25/25 = 22/25 + 2/25 + x
x = 25/25 - (22/25 + 2/25)
x = 25/25 - 24/25
x = 1/25
1/25 * 500 kg = 500 / 25 * 1 = 20 * 1 = 20 kg
