Even if the quantity doesn't decrease, the percentage will.

from A little less, others more.

• Even if the quantity doesn’t decrease, the percentage will.
• 
• 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.

relevance - When the rate is reported, look at the quantity; when the quantity is reported, look at the rate.
