The mass of Denise's rock sample is 684 grams. The mass of Pauline's rock sample is 29,510 centigrams. How much greater is the mass of Denise's sample than Pauline's sample?
"centi" is 100. 1 centigram is 100 grams, so Denise's sample is 68,400 centigrams. 68400 - 29510 = 38890 centigrams or 388.90 grams.
