Example
Mr. Ramírez uses a ratio of 1 part pork to 3 parts beef when he makes meatloaf.
He needs 32 oz of meat. How many ounces of beef and how many ounces of
pork does Mr. Ramírez need for his meatloaf?
You can use a tape diagram to relate the parts to the total.
Divide the total amount by
1 part
the number of equal parts
to find the value of each part.
Pork
8 oz
Total:
32 oz of meat
4 parts
32 oz + 4 =8 oz
Beef
8 oz
8 oz
8 oz
Pork: 1 X 8 oz = 8 oz
Beef: 3 X 8 oz = 24 oz
3 parts
Mr. Ramírez needs 8 oz of pork and 24 oz of beef.
1 Suppose Mr. Ramírez from the Example needs 40 oz of meat.
a. What changes would you need to make to the tape diagram?
b. How many ounces of pork and how many ounces of beef would Mr. Ramírez
need for a meatloaf with 40 oz of meat?
