Calculate and correct to two significant figures, the percentage error in approximating 0.375 to 0.4

  • 2.0
  • 2.5
  • 6.6
  • 6.7 checkmark

The correct answer is: D

Explanation

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%
