Answer 2

Answer:

$cost \: of \: 12 \: bananas = 15 \\ cost \: of \: 1 \: banana \: \: \: \: = \frac{15}{12} = \frac{5}{4}$

$cost \: of \: 8 \: oranges = 40 \\ cost \: of \: 1 \: orange \: \: = \frac{40}{8} = 5$

so,

$\frac{ \frac{5}{4} }{5} = \frac{5}{4} \times \frac{1}{5} = \frac{1}{4}$

so the required ratio is 1:4
