For 876, we keep 8and round up, because 7the digit after (the second significant digit) is 6, which is greater than 5. Therefore, we get 880. Rounding decimals The same principles apply when rounding decimals. The key difference is how we handle trailing zeros. For example: Round 9.
05675to three significant figures : We retain 9.05and list of new zealand fax number up, because the next digit ( 6) is greater than 5, and the result is 9.06. Round 0.01234to three significant figures : We keep 0.012and retain the last digit because the next digit ( 4) is less than 5, and the result is 0.
012. Practical application: Calculating the final price Imagine that you buy a dress with a base price of $15 and are charged an additional 6.25% in income tax. To understand how much you actually pay, you first need to calculate the tax: Tax calculation :6.25% of 15 = (15/100) × 6.
