roses at a flower shop are sold in packages of 12. each package contains 4 red roses. how many red roses will you get if you buy 60 roses?



Answer :

If we buy  60 roses we buy 60/12=5 packages. 
4.5=20 red roses.

The ratio of red roses to all roses is [tex]\tfrac{4}{12} = \tfrac{1}{3}[/tex]

Since the number of red roses is proportional in all the packages, the equation we are trying to solve is:

[tex]\frac{1}{3} = \frac{x}{60}[/tex]

[tex]1 \cdot 60 = 3 \cdot x[/tex]

[tex]x =\frac{60}{3} = \boxed{20}[/tex]

Hope this helps :D
