Im not so good at math, but i have a question thet i know the answer too, but i think i have made a wrong way:

an apple = 2 kr (thats the danish valuta)

an orange = 4 kr

I have bought 32 pices for 104 kr

how many oranges have i bought?

I now that he have bought 20 oranges and 12 appels

but do anyone know an easier way i could have gotten to this answer?
