Question

Sebastian made 1/2 of a recipe and used 2/3 cups of olives. how many cups of olives are required for a whole recipe

Answer 1

`\begin{gathered} \text{we can apply the rule of thre}e\text{ in this case:} \\ (1)/(2)\text{recipe -------}(2)/(3)\text{cups} \\ 1\text{ recipe ------- x cups} \\ \text{hence} \\ x=((1)((2)/(3)))/((1)/(2)) \\ x=((2)/(3))/((1)/(2)) \\ x=(2\cdot2)/(3\cdot1) \\ x=(4)/(3)\text{cups} \end{gathered}`
