You may change the labels (boys and girls) to other quantities that you want to discuss. [br]We are interested in describing A as a percentage of B (of B as a percentage of A). [br][br]This comparison is different from using percentage to describe part-whole relation and is generally more challenging. It depends on which quantity is chosen as the reference for comparison and requires understanding of percentages beyond 100%. [br][br]Use the percentage ruler to visualise the required percentages by dragging the 100% mark to match one of the quantities. [br][br]You can still talk about part-whole relation by showing the 'total'.
