Mike wants to make meatloaf. his recipe uses 7lbs of meat. if he uses a 3 to 1 ratio of beef to pork, how much pork will je use? enter your answer as a mixed number in simplest terms

The total quantity of meatloaf that Mike uses for his recipe = 7 pounds
The ratio of beef to pork that needs to be used = 3:1
Let us assume the common ratio to be = x
Then
3x + x = 7
4x = 7
x = 7/4
So
The amount of pork that is
needed for the recipe of Mike = 1 * (7/4) pounds
                                               = (7/4) pounds
                                               = 1 3/4 pounds
So the quantity of pork that is required to make the recipe of Mike is 1 3/4 pounds. I hope the procedure is simple enough for you to understand.
