Calculate and correct to two significant figure... - WAEC Mathematics 2002 Question
Calculate and correct to two significant figures, the percentage error in approximating 0.375 to 0.4
A
2.0
B
2.5
C
6.6
D
6.7
correct option: d
Measured value = 0.375
Approximation = 0.4
Error = 0.4 - 0.375 = 0.025
Error% = \(\frac{0.025}{0.375}\) x 100% = 6.67% = 6.7%
Approximation = 0.4
Error = 0.4 - 0.375 = 0.025
Error% = \(\frac{0.025}{0.375}\) x 100% = 6.67% = 6.7%
