Round the length 7.96 to one decimal place and enter the number.
الإجابة الصحيحة
8 ± 0.001
الشرح
The hundredths digit is 6, so the tenths digit 9 increases and carries, making 7.96 round to 8.0 at one decimal place. Entering 7.9 would incorrectly leave the retained digit unchanged despite a deciding digit above 4.
