formula for percentage error.

[( I  Approximate Value - Exact Value  I ) / Exact Value] x 100   [note the two bars in the eqation are the bars of Absolute Value Symbol I  I

Approximate value =144.3 mm =14.43cm

Exact value= 144 cm

[(I  14.43cm-144 cm  I ) /144 cm ] x 100

[(I  -129.57 cm  I ) /144 cm ] x 100

[( 129.59 cm  ) /144 cm ] x 100

[0.899 cm ] x 100

[0.90 cm ] x 100

90%  ANS
