I have been learning ratio and proportion lately and my teacher gave me this sum.
If 7 oranges cost 700$, then how much will 60 oranges cost.
She made a table which had 2 headings : Number of oranges and cost.
Then she told me let the number of oranges be x and the cost be y.
Then she came to the conclusion that x / y = k where k is the constant of proportionality.
Can anyone please tell me what is the constant of proportionality and how did she derive the formula x/y = k
All help is appreciated!
