Question

Ellie has 4 quarters for every 5 pennies in her change purse. How many pennies would she have if she has 16 quarters?

Answer 1

Sh would have 20 pennies because for every 5 pennies there 4 quarters so , if she has 16 quarters she would have 20 pennies

Answer 2

$\frac{4 quarters}{5 pennies} = \frac{16 quarters}{x pennies} \\ \frac{4quarters*4=16quarters}{5pennies*4=20pennies}$
The answer is fifteen pennies, because 16/4 is 4, so you multiply 5 by 4 to get 20. Hope this helps!
