The errors on scale 1 and scale 2 are 15% and 6%.
Percentage
The amount of something is expressed as if it is a part of the total which is a hundred. The ratio can be expressed as a fraction of 100. The word percent means per 100. It is represented by the symbol ‘%’.
Given
Scale 1, measured weight = 85, and actual weight = 100.
Scale 2, measured weight = 47, and actual weight = 50.
To find
The error in each scale.
How to find the error?
Error % is given by the formula,
[tex]\rm Percent\ error\ =\ \dfrac{actual\ value\ -\ measured\ value}{actual\ value} * 100[/tex]
For scale 1
Measured weight = 85, and actual weight = 100.
[tex]\rm Percent\ error\ =\ \dfrac{actual\ value\ -\ measured\ value}{actual\ value} * 100\\\\\rm Percent\ error\ =\ \dfrac{100-85}{100} * 100\\\\\rm Percent\ error\ =\ 15[/tex]
For scale 2
Measured weight = 47, and actual weight = 50.
[tex]\rm Percent\ error\ =\ \dfrac{actual\ value\ -\ measured\ value}{actual\ value} * 100\\\\\rm Percent\ error\ =\ \dfrac{50-47}{50} * 100\\\\\rm Percent\ error\ =\ 6[/tex]
Thus the error in scale 1 and scale 2 is 15% and 6%.
