Question

chemistry

Answer 1

reminder: for addition/subtraction, look at which number has the least # of decimal places

1st problem: 1.40 has 2 decimal places ---> round the answer to 2 decimal places
2nd problem looks good
3rd problem: 8.8 has 1 decimal place ---> round to 1 decimal place

Answer 2

1.4 and 8?

Answer 3

when you're rounding, round the *answer* not the numbers inside the problem

4.927 - 1.40 = 3.527 ---> round to 2 decimal places ---> 3.53
same logic w/ problem 3

Answer 4

1.40 and 8.8?

Answer 5

like I said, only round *** at the end ***

problem 3 is 8.8 + 0.97

do **not** round 8.8 or 0.97. add 8.8 + 0.97, and ***then** round.

Answer 6

9.8?

Answer 7

yes good

Answer 8

3.0?

Answer 9

3.0?

Answer 11
