Any such equality will not dictate the sig figs in your final answer. G. More examples: 1. 3340 x 1.2 = 4.0 x 103 The answer must have 2 sig dig cause of the 1.2 thus 4000 is incorrect because it only has 1 sig dig. 2. 88359 / 3 = 30000 The answer can only have 1 sig dig cause of the 3.

Below are two examples. A) Write the product of 2.10 × 0.5896 with the correct number of significant figures. Step 1) 2.10 × 0.5896 = 1.23816 Step 2) 1.23816 = 1.24 (three sig. figs because 2.10 has three) The answer is 1.24 B) Write the quotient of 16.15 / 2.7 with the correct number of significant figures. Step 1) 16.15 / 2.7 = 5.98148148
