Kyle and Dylan are trying to figure out the best approximation for V11. Both truncated the decimal expansion, which is 3.316, to the nearest hundredth. Looking at their answers on the number line, which student, if either, truncated correctly? Justify
A)
B)
Kyle: To truncate the decimal expansion to the hundredths, drop the 6
without rounding. The correct answer is 3.31.
Dylan; To truncate the decimal expansion to the hundredths, round to the
nearest hundredth. The correct answer is 3.32
Neither: To truncate the decimal expansion to the hundredths, drop the 6
and change the 1 to a 0. The correct answer is 3.30
Neither: To truncate the decimal expansion to the hundredths, round to the
nearest tenth and affix a zero. The correct answer is 3.30
D)
