Question

Under very specific instructions, a jeweler made one ring for the queen and one ring for the princess. The gem on the queen's ring weighed 9/10 of a carat and the stone on the princess's ring weighed 7/10 of a carat. How much heavier was the stone on the queen's ring than the stone on the princess's?

Answer 1

Answer: 1/5

Explanation:

From the question, we are informed that the gem on the queen's ring weighed 9/10 of a carat and the stone on the princess's ring weighed 7/10 of a carat.

To calculate how heavier the stone on the queen's ring was than the stone on the princess will be:

= 9/10 - 7/10

= 2/10

= 1/5
