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
[tex]\Rightarrow \dfrac{\text{Deviation }}{\text{Actual value}}\times 100[/tex]
Insert the values
[tex]\Rightarrow \dfrac{30-24}{24}\times 100\\\\\Rightarrow \dfrac{6}{24}\times 100\\\\\Rightarrow 25\%[/tex]
Therefore, the percentage error is 25%.
