To find out how many more rings than bracelets Mrs. Smith has, you need to calculate the difference between the number of rings and the number of bracelets.
First, write down the total number of rings. Mrs. Smith has 645 rings.
Next, write down the total number of bracelets. Mrs. Smith has 456 bracelets.
Now, subtract the number of bracelets from the number of rings. In mathematical terms, this operation looks like this:
645 (rings) - 456 (bracelets)
This calculation will give us the difference between the two numbers. Performing this operation gives us 189.
So, Mrs. Smith has 189 more rings than bracelets. Therefore, the correct answer is a) 189 rings.
AnswerL a) 189 rings
