Okay make an proportion:
240 x
____=________
250 100
Now do 240×100=24000
24000÷250= 96
100-96=4
So 4%
Answer: 4.17%
Step-by-step explanation:
Given : A student estimated a mass to be 250g but upon carefully measuring it found the actual mass to be 240g.
The formula to find the percent error is given by :-
[tex]\%\text{ error}=\dfrac{|\text{Estimated value - Actual value}|}{\text{Actual value}}\times100\\\\=\dfrac{|250-240|}{240}\times100\\\\=\dfrac{10}{240}\times100\\\\=4.16666666667\approx4.17\%[/tex]
Hence, the percent error = 4.17%
