The experimental value ( the height of the go wished frame) = 1.34 m
The true value. ( the supposed height) =1.25 m
The formula for percents error
[tex] \frac{experimental \: value - true \: value}{true \: value} \times 100[/tex]
[tex] \frac{1.34 - 1.25}{1.25} \times 100[/tex]
Subtract 1.34 by 1.25
[tex] \frac{0.09}{1.25} \times 100[/tex]
Divide
[tex]0.072 \times 100[/tex]
Multiply to convert 0.072 to percent
Percent error = 7.2%
