Well, you can express it any way you like. Math is flexible that way! Note that from 4.8% to 5.3% is actually an increase by 10%, namely: 0.048 * 1.1 = 0.053,

Well, you can express it any way you like. Math is flexible that way! Note that from 4.8% to 5.3% is actually an increase by 10%, namely: 0.048 * 1.1 = 0.053, or 4.8% * 110% = 5.3%. I imagine you're looking at it and seeing the difference between percentages (0.5%), not the ratio between them (1.1), a distinction that trips people up not infrequently.
