Answer 2

82.8 cm measured to the nearest tenth of a cm is 80cm.

• When we deal with decimal values while taking measurements we round off the figure to the nearest ten unit for simplicity of the measurement.

• While rounding off we consider the ten unit which has minimum numerical difference,both negative and positive.

• Here,the measurement is closest to 80 and that's why we choose 80 over 90, inspite of the negative difference.
