Using proportions, it is found that:
A. 0.5 pounds of butter.
B. 1.25 gallons of cream.
- These questions are solved by proportions, using a rule of three, due to the relation given(0.5 gallon of cream - 1 pound of butter).
Item a:
- x pounds for 0.25 gallons.
The rule of three is:
0.5 gallon of cream - 1 pound of butter
0.25 gallons of cream - x pounds of butter
Applying cross multiplication:
[tex]0.5x = 0.25[/tex]
[tex]x = \frac{0.25}{0.5}[/tex]
[tex]x = 0.5[/tex]
Thus, you could make 0.5 pounds of butter.
Item b:
0.5 gallon of cream - 1 pound of butter
x gallons of cream - 2.5 pounds of butter
[tex]x = 2.5(0.5) = 1.25[/tex]
You would need 1.25 gallons of cream.
