Determining the Mass of Precious Stones and Pearls

To determine the mass of precious stones and pearls, a unit of mass called a carat is used. One carat is equal to one-fifth of a gram. If the mass of a large pearl is 20 carats, we can calculate its mass in grams.

To convert carats to grams, we can use the following conversion factor:

1 carat = 1/5 gram

Therefore, to find the mass of the large pearl in grams, we can multiply the number of carats by the conversion factor:

Mass in grams = 20 carats * (1/5 gram/carat)

Simplifying the equation:

Mass in grams = 20/5 grams

Calculating the result:

Mass in grams = 4 grams

Therefore, the mass of the large pearl is 4 grams.
