(a) 67.8 + 968 + 3.87 (b) 463.66 + 29.2 + 0.17 (c) 16.36 + 287.345 + 682.23 (d) 68.7 - 23.95 (e) 0.09875 - 0.0875 (f) 0.1927 - 0.035 (g) (2.6)(42.2) (h) (65)(0.041)(325) (i) (0.0060)(26)(55.1) (j) (3.275 × 105)(1.0375 × 10-2) (k) (1.625 × 10-3)(7.3 × 10-4) (l) (3.9087 × 10-3)(4.920 × 107) 2 years ago 2 years ago

For example, in b), your answer would be 493.03, but when you add/subtract, the sig. fig. depends on the smallest amount of digits after the decimal in the problem (in this case, it would be 29.2<- so your answer would be 493.0) When you multiply/ divide, the number of sig fig your final answer will have depends on the number with the least significant digits: ex, g) =109.72 but no. of sig figs will 2 so it will equal $1.1 \times 10^{2}$
