 
Richard, I would start by constructing a table of fruit that balance.
What I see is that 5 bananas balance with 3 pears so 10 bananas balance with 6 pears, so I can add another line
Thus 8 oranges balance with 6 pears.
We don't need the banana rows now so I can reduce the table to
I can now reduce each row by dividing by 2
Can yo see how to proceed,
