Round the science reading 6.274 to two decimal places and enter the number.
الإجابة الصحيحة
6.27 ± 0.001
الشرح
To keep two decimal places, inspect the thousandths digit in 6.274; it is 4, so the hundredths digit stays 7 and the result is 6.27. Rounding the 4 upward would wrongly use a threshold below 5.
