Question

A sack of Nickels has a mass of 45 g. There are 9 nickels in the stack

Answer 1

To do this you will take the mass of the sack which is 45g.

Divide this amount by the number of nickels in the sack which is 9.

$45 \div 9 = 5$

So the mass of one nickel is 5g.

Answer 2

Hello there!

9 nickels = 45g

1 nickel = ?

Then cross multiply that

45 * 1 = 9 * x

45 = 9x

x = 45/9

x = 5
