Answer 1

we can look at it this way, if 60 grams of Cocoa make 20 cupcakes, how many cupcakes make 210 grams?

`\begin{array}{ccll} Cocoa&Cupcakes\\ \cline{1-2} 60 & 20\\ 210& x \end{array} \implies \cfrac{60}{210}~~=~~\cfrac{20}{x} \\\\\\ \cfrac{2}{7} ~~=~~ \cfrac{20}{x}\implies 2x=140\implies x=\cfrac{140}{2}\implies x=70`
