The percentage decrease quantifies how much a quantity reduces in relation to the original amount. It is calculated by dividing the decrease by the original amount and then multiplying by 100. This value provides a standardized measure to compare reductions of different quantities.

Density is a measure of how much mass is contained in a given volume of a substance, while relative density is the ratio of the density of a substance to the density of a standard substance (usually water). Relative density is a dimensionless quantity used for comparison purposes.
Distance is a sclar quantity. A scalar quantity is a magnitude only. A vector has magnitude and direction. Distance AND direction is a vector quantity.

times 3. For example, Three times as much of 7 is 3*7 = 21 Three times as much of 10 is 3*10 = 30
Since that is close to its half-life, about half the original quantity will be left.
A ratio of 1 to 100 means that for every one unit of the first quantity, there are 100 units of the second quantity. This can indicate a relationship or comparison, such as in finance, where it might represent a proportion of investment to total assets. It illustrates a significant disparity between the two values, emphasizing that the second quantity is much larger relative to the first.
Quantity refers to an amount, value, 'how many', how much'

If pH decreases by 1 unit on the pH scale, it means the concentration of hydrogen ions has increased by a factor of 10. For example, if the original pH was 7 and it decreases to 6, then the concentration of hydrogen ions has increased by 10 times.
