31.5 of 473 = 31.5*473 = 14899.5
The answer depends on the units sued for 472.9 It should be obvious that 472.9 centimetres and 472.9 inches, for example, will round to different answers.
To estimate by rounding each number to its leading digit, first identify the most significant digit in each number. Then, round that digit to the nearest multiple of ten based on its place value. For example, if you have the number 473, the leading digit is 4, which rounds to 400. Once all numbers are rounded this way, you can sum them for an estimated total.
