Mathematics for IGCSE & O level - Limits Of Accuracy (Section 1 - No. 3)
A mass is given as 0.634 kg to the nearest gram. Between which two values does the mass lie?
0.633 kg and 0.635 kg
0.6335 kg and 0.6345 kg
0.63 kg and 0.64 kg
0.634 kg and 0.635 kg
توضيح
Since the measurement is to the nearest gram (0.001 kg), the lower bound is 0.634 - 0.0005 = 0.6335 kg and the upper bound is 0.634 + 0.0005 = 0.6345 kg.
