Question

Okay I'm going to post a question in 2 pictures, but you have to read across. (sorry if it's confusing :/ )

Answer 1

okay here it is!

Answer 2

When you sum or subtract two measurements the result should have as many digits after the decimal point as there are in the individual measurement with the least no. of digits after the decimal point.

Answer 3

eg.
3.65+2.142=5.792=5.79

Answer 4

In case of multiplication or division, the result should have as many sigfigs as there are in the measurement with the least n o of sigfigs

Answer 5

so the 1st blank and 2nd blanks would be 3 sig figs? but i thought that the last blank would need 2 sig figs, since the difference is .6, but it needs to have 2 decimal places, which becomes .60 with 2 sig figs. And 3, 3, 2 isnt an option...
