Question

4.05 kg + 567.95 g + 100.1 g add the correct value using the correct sig figs and or least precise degree of precision.

When i did least degree of precision i got 4718.1g, do we need to convert the kg unit to grams before getting the least degree of precision? since i used 100.1 as dop and if i had converted first the dop of 4.05 or now 4050g the dop is now only to the tens place compared to being in the tenths place

Answer 1

To get the least degree of precision I would model it after the kg amount or 4.05 or two decimal places so I would add 0.56795 or to two places would be 0.57 kg and then 0.1001 kg would be 0.1 kg so my answer would be 4.72 kg. In contrast, the greatest degree of precision would be 4050g + 567.95 grams plus 100.1 g= 4718.05 grams or 4.71805 kg. At least that is what I would think..
