First, identify the first non-zero digit, which is 4. Leading zeros (the zeros before 4) are NOT significant—they only indicate the position of the decimal point. Count 2 significant figures from 4: we get 4 and 5, giving us 0.0045. Now check the next digit (6). Since 6 ≥ 5, we round UP, changing the 5 to 6. Therefore, 0.004567 becomes 0.0046. Remember: in ECZ exams, losing marks often happens due to incorrect rounding, so always check the digit after your last significant figure.
