Percentage:

• A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics.
• If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100.
• The proportion, therefore, refers to a component per hundred.
• Per 100 is what the word percent means.

Example -

1. An increase of $$0.15$ on a $$2.50$ price equals a fractional increase of $\frac{0.15}{2.50} =0.06$.
2. This represents an increase of % when expressed as a percentage.
3. There is no mathematical restriction, therefore percentages may have various values even though the majority of % numbers fall between $0$ and $100$.
4. For percent changes and comparisons, it's typical to use terms like $111$ percent or $35$ percent.

Therefore, the correct options are as follows -

(A) The amount of change is different for the percent increase and the percent decrease.

(C) The ratio for the percent increase has a smaller denominator than the percent decrease.

(D) The ratio for the percent increase has a different numerator than the percent decrease.
