Answer:

The mass of one nickel is 5 grams.

Step-by-step explanation:

This question can be solved by proportions, using a rule of three.

In this question:

9 nickels have a mass of 45 grams. So one nickel will have a mass of:

9 nickels - 45 grams

1 nickel - x grams

Applying cross multiplication

9x = 45

x = \frac{45}{9} = 5

The mass of one nickel is 5 grams.
