Answer
Die verhouding 2 : 4 : 3 (X) verteenwoordig die verhoudings van stikstof, fosfor en kalium in die kunsmis, bekend as die NPK verhouding.

Answer
Om die waarde van X te bereken, gebruik ons die verhouding:
rac{2}{X} = rac{4}{2.315}
Hieruit kan ons X bereken:
X = rac{2 imes 2.315}{4}
ightarrow X = 1.1575 ext{ kg}
$$.
