A 55 gallon drum of oil is to be used to fill cans that hold 2 quarts each. How many cans can be filled from the drum ?.
The correct answer and explanation is:
To solve this problem, we need to convert gallons to quarts and then determine how many 2-quart cans can be filled from a 55-gallon drum of oil.
First, we need to know how many quarts are in one gallon. Since there are 4 quarts in 1 gallon, we can multiply the number of gallons by 4 to convert to quarts.
55 gallons × 4 quarts per gallon = 220 quarts
Now that we know the drum contains 220 quarts of oil, we can figure out how many cans, each holding 2 quarts, can be filled by dividing the total number of quarts by the capacity of each can.
220 quarts ÷ 2 quarts per can = 110 cans
Therefore, 110 cans can be filled from the 55-gallon drum of oil.
This problem involves simple conversion and division. First, we convert gallons to quarts, ensuring we have the right measurement. After conversion, we divide the total number of quarts by the number of quarts each can holds to determine how many cans can be filled.
In summary, the key steps to solve this are:
- Convert gallons to quarts (multiplying by 4).
- Divide the total quarts by the can capacity to find the number of cans.
- The result is 110 cans, meaning the entire 55-gallon drum of oil can fill 110 two-quart cans.
