We are told in the question that 1 carat is equal to 200 mg.

The Hope Diamond is 44.5 carats. Let's multiply the weight of 1 carat by 44.5 to get the weight of the Hope Diamond in mg:

[tex] \frac{200mg}{1 carat}* \frac{44.5 carats}{1}=8,900 mg [/tex]

The total weight of the Hope Diamond is 8,900 mg. However the question asks for the weight in grams. There are 1000 mg in 1 gram, so let's divide the known weight of the Hope Diamond in mg by 1000 to get the weight converted to grams:

[tex] \frac{8,900mg}{1000}=8.9grams [/tex]

Now we know that the weight of the Hope Diamond is equal to 8.9 grams.
