Question

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 Denise's sample than Pauline's sample?

Answer 1

Denise's rock sample has `38,890` centigrams (`388.9` grams) more mass than that of Pauline.

Explanation:

One gram is equal to `100` centigrams. Hence, Denise's rock sample of 684 grams can be expressed as `(684xx100)=68,400` centigrams.

Pauline's rock sample is `29,510` centigrams.

The difference between the two rock samples is:

`68400-29510=38890`

Denise's rock sample has `38,890` centigrams more mass than that of Pauline.
