im still kinda confused (im bad at this type of qns)
We attempt this question in a ratio format as though it is a primary school question.
2 boxes --> 48 apples
1 box --> 24 apples
5 boxes --> 120 apples
Here it's similar.
q cents --> p oranges.
We need to find out the number of oranges which can be bought by 1 cent. This is found by dividing both sides by q.
1 cent --> p/q oranges
Now we need to find out the number of oranges which can be bought by r dollars, or 100r cents. We multiply both sides by 100r.
100r cents --> 100pr/q oranges
2 boxes --> 48 apples
1 box --> 24 apples
5 boxes --> 120 apples
