We find out what the mass of the alloy should be if it contains 2.4 kilograms of iron, provided that the alloy weighing 16 kilograms contains 6.4 kilograms of iron:
16 kg – 6.4 kg iron
x kg – 2.4 kg of iron
x = 2.4 × 16: 6.4;
x = 38.4: 6.4;
x = 6 (kg) – the mass of the alloy, which contains 2.4 kilograms of iron.
Thaws: the mass of the alloy is 6 kilograms.
