If the quantity of one thing A does not decrease, but the quantity of another thing B increases, then the proportion of A in the total of A and B will decrease.
Although it looks obvious in the figure, some people focus on the words "decrease or not decrease" and think in a way that blurs the distinction between quantity and percentage.
When we're talking about "decreasing proportions," it doesn't matter whether the quantity is decreasing or not, because even if the quantity of A is increasing, if the quantity of B is increasing faster, then the proportion of A is decreasing.
