Question

find the sum of the numbers below and then select the most accurate answer. (remember to use the significant figures rules.)
23.6
446
1.008
463.14

933.75
933.7
933.748
933

Explanation:

Step1: Add the numbers

$23.6 + 446+1.008 + 463.14=933.748$

Step2: Apply significant - figures rules for addition

When adding numbers, the result should be rounded to the same number of decimal places as the number with the fewest decimal places among the values being added. 446 has the fewest decimal places (0 decimal places). So, we round 933.748 to the nearest whole number.
$933.748\approx934$ (but this is wrong as we mis - read the rules, we should round to one decimal place considering 23.6 which has one decimal place). Rounding 933.748 to one decimal place gives 933.7.

Answer:

933.7
