- A student multiplied a number by 3/5 instead of 5/3.
Question 1:
A student multiplied a number by 3/5 instead of 5/3.What is the percentage error in the calculation?
A. 34%
B. 44%
C. 54%
D. 64%
Feedback Let the number of students be x.
Then, error = (5/3)x - (3/5)x = (16/15)x.
Error % = [ (16x/15) X (3/5x) X 100 ]% = 64%
Then, error = (5/3)x - (3/5)x = (16/15)x.
Error % = [ (16x/15) X (3/5x) X 100 ]% = 64%
