Show more Show more WebExample 1: finding upper and lower bounds. A number was given as 38.6 to 3 significant figures. Find the upper and lower bounds of the number. Identify the place value of the degree of accuracy stated. The place value of the degree of accuracy is 0.1. 2 Divide this place value by 2. 0.1 ÷2 =0.05 0.1 ÷ 2 = 0.05.
