The ratio (r) between the # of eggs and the # of bananas in each recipe is given by the quotient:
[tex]r=\frac{\text{ \# of bananas}}{\text{ \# of eggs}}.[/tex]We compute the ratio of each recipe:
[tex]\begin{gathered} r_A=\frac{3}{6}=0.5, \\ r_B=\frac{2}{4}=0.5, \\ r_C=\frac{1}{3}\cong0.333, \\ r_D=\frac{3}{8}=0.375. \end{gathered}[/tex]We see that we have:
[tex]r_A=r_B=0.5.[/tex]We conclude that recipe A and B use the same ratio of eggs
AnswerA. Recipe A and recipe B.
