Percentage is a part of a whole. The percentage change in the number of paper clips is 12.5%.
Given to us
Number of Paper clips Initialy= 72
Number of Paper clips now = 63
We know that the paper clip, in the beginning, was 72 but later on it was reduced to 63. therefore, the paper clips were reduced from the initial value.
\(\text{Percentage change} =\rm \dfrac{Initial\ value\ - final\ value}{Initial\ value} \times 100\)
Substitute the value,
\(\text{The percentage change in the paperclip } =\rm \dfrac{Initial\ value\ - final\ value}{Initial\ value} \times 100\)
\(\begin{aligned}\text{The percentage change in the paperclip } &=\rm \dfrac{72-63}{72} \times 100\\\\&= 12.5\% \end{aligned}\)
Hence, the percentage change in the number of paper clips is 12.5%.
