Explanation
% error = erroractual value×100

error = N72 - N68 = 4

actual value = N72

%error = 4/72×100

= 100/18=50/9 = 5 whole no 5/9%

(72-68/72)*100.
( 4 /72) * 100.G
(400/72)
(5+5/9)% -B.

error = 72-68 = 4
actual change = 72
%error = error/actual change x 100
%error = 4/72 x 100
= 1/18 x 100
= 100/18
= 50/9
= 5 5/9% (read as 5 whole number 5 over 9)
= i. e (5+5/9)% B
