Question 1180116: "We're hungry!" yelled Martina's sister and brothers. "Where are the pancakes?" Martina didn't pay any attention. She was trying to figure out how to measure out 24 ounces of milk. She had 3 different cans, marked 12
ounces, 6 ounces, and 4 ounces. Each can had just one number marked on it. How many different ways could Martina measure 24 ounces of milk? Write to help explain your best thinking using words, numbers, or pictures.

The required 24 ounces is 12 ounces twice.
12 ounces can be made using...
(a) the 12-ounce can once; or
(b) the 6-ounce can twice; or
(c) the 4-ounce can three times.
So the 24 ounces can be obtained with...
(1) (a)+(a): 12 + 12
(2) (a)+(b): 12 + 6 + 6
(3) (a)+(c): 12 + 4 + 4 + 4
(4) (b)+(b): 6 + 6 + 6 + 6
(5) (b)+(c): 6 + 6 + 4 + 4 + 4
(6) (c)+(c): 4 + 4 + 4 + 4 + 4 + 4
ANSWER: She can measure 24 ounces in 6 different ways.
