Answer: option (b) 1 dgExplanation:1) These are the different equivalents of these amounts: (a) 1 g = 100 cg ⇒ 1 cg = 0.01 gb) 1 g = 10 dg ⇒ 1 dg = 0.1 gc) 1 g = 1000 mg ⇒ 1 mg = 0.001 gd) 1 g = 10 ⁹ g ⇒ 1 ng = 10 ⁻⁹g2) Now that you have all the masures in grams that can be compared:0.1 g > 0.01 g > 0.001 g > 10 ⁻⁹g3) Thus, the largest value is 0.1 g which is 1-dg.
