The required multiplier for 21.6% decay is 78.4%.
Given that,
To find the multiplier for 21.6% decay
What is percentages?
The percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.
What is simplification?
The process in mathematics to operate and interpret the function to make the function simple or more understandable called simplifying and the process is called simplification.
In the question, the multiplier for the rate of 21.6% decay is to be determined.
A multiplier of decay implies decay = 1 - r
Since let the Decay multiplier be x
x = 1 - r
x = 1 - 0.216
x = 0.784
x = 78.4%
Thus, the required multiplier for 21.6% decay is 78.4%.
