To answer this question, we need to have into account the ratio between the chocolate and the nuts. This ratio is:
[tex]\frac{4}{6}=\frac{2}{3}[/tex]That is, simplifying the ratio, we have 2 parts of chocolate and 3 parts of nuts. This ratio must be the same for the tablespoon. Then, if we have 18 tablespoons of nuts, then we can pose the situation as follows:
[tex]\frac{4}{6}=\frac{2}{3}=\frac{x}{18}\Rightarrow x=\frac{2\cdot18}{3}\Rightarrow x=\frac{36}{3}\Rightarrow x=12[/tex]Therefore, we need 12 tablespoons of chocolate to follow the recipe for the party.
