The fraction on the left represents A out of B slices of a rectangular pizza( 1 ).

- init({ range: [ [0, 1], [0, 1] ], scale: [180, 25] }); - rectchart( [A, B - A], ["#e00", "#999"] ); + init({ range: [ [0, 1], [0, 1] ], scale: [475, 25] }); + rectchart( [A, B - A], [RED, GRAY] );

What if we cut the pizza( 1 ) into D slices instead? How many slices would result in the same amount of pizza( 1 )?

- init({ range: [ [0, 1], [0, 1] ], scale: [180, 25] }); - rectchart( [0, D], ["#e00", "#999"] ); + init({ range: [ [0, 1], [0, 1] ], scale: [475, 25] }); + rectchart( [0, D], [RED, GRAY] );

We would need C slices.

- init({ range: [ [0, 1], [0, 1] ], scale: [180, 25] }); - rectchart( [C, D - C], ["#e00", "#999"] ); + init({ range: [ [0, 1], [0, 1] ], scale: [475, 25] }); + rectchart( [C, D - C], [RED, GRAY] );

\dfrac{A}{B} = \dfrac{C}{D} and so the answer is C.
