Question: Practice using the rule by rounding the answer to the correct number of significant figures. Write the unrounded answer first , then write the answer

Practice using the rule by rounding the answer to the correct number of significant figures. Write the unrounded answer first, then write the answer rounded to the correct number of significant figures.

Example Problem: 2.55 cm x 3.14 cm = 8.007 cm² = 8.01 cm²

6 x 0.30 =
0.03 x 7 x 210 =
11.6 x 6.24 =
0.004 x 5280 =
500.55 5.11 =
1000 8.2 =
51.6 x 31.4 =
8088 x 0.4 =
204.17 3.2 =
31.2 x 4.1 =
8000 9.7 =
35.45 x 6.1 =
1.1 x 3.25 =
1000 19.7 =
10.0 x 0.02 =

Example Problem:

35.6 + 56.27 =
4.337 + 84.7128 =
6.2 + 4.114 =
7.331 + 12.42 =
22.5285 + 22.14 + 4.266 =
88.489 + 7.133 + 6.5 =
48.835 - 9.1 =
16.221 - 8.28 =
101.12 - 98.7 =
13.7 + 25.466 =
45.758 - 33.22 =
19.6 - 8.77 =
23 + 16.4 + 22.0 =
24.5764 - 1.9833 =
8.31 + 7.2 + 9.4626 =
