Shalnov [3]

Answer: 25%

Step-by-step explanation:

Given

Emelia measures the weight of the rock to be 30 gm

The actual weight was 24 gm

Percentage error is given by

$\Rightarrow \dfrac{\text{Deviation }}{\text{Actual value}}\times 100$

Insert the values

$\Rightarrow \dfrac{30-24}{24}\times 100\\\\\Rightarrow \dfrac{6}{24}\times 100\\\\\Rightarrow 25\%$

Therefore, the percentage error is 25%.
