4 bananas / 12 oranges reduce by common factor 4
1 banana / 3 oranges
For every 1 banana you have 3 oranges.
Ratios do not say how many of any one thing you have. It only says that for so many of one you have so many of another.
You could have 10 bananas and 30 oranges, or 22 bananas and 66 oranges.
