A jar contains 26 fluid ounces of spaghetti sauce

A jar contains 26 fluid ounces of spaghetti sauce. How many cups of spaghetti sauce do 4 jars contain?

The correct answer and explanation is:

To determine how many cups of spaghetti sauce 4 jars contain, you first need to know how many cups are in one jar.

1. Conversion from fluid ounces to cups:
   • 1 cup is equivalent to 8 fluid ounces.
   • The jar contains 26 fluid ounces, so to convert fluid ounces to cups, divide the total fluid ounces by 8.
   Cups per jar=26 fluid ounces8=3.25 cups per jar\text{Cups per jar} = \frac{26 \text{ fluid ounces}}{8} = 3.25 \text{ cups per jar}
2. Calculating for 4 jars:
   • Since each jar holds 3.25 cups, the total amount for 4 jars would be:
   Total cups=4×3.25=13 cups\text{Total cups} = 4 \times 3.25 = 13 \text{ cups}

Thus, 4 jars contain 13 cups of spaghetti sauce.

Explanation

To solve this, you need to apply the concept of unit conversion. The question gives you the volume of sauce in fluid ounces, but the answer is required in cups. The key conversion factor is that 1 cup equals 8 fluid ounces. So, by dividing the fluid ounces in one jar (26 ounces) by 8, you get the number of cups per jar, which is 3.25 cups.

After calculating how many cups are in one jar, multiply that by the number of jars (in this case, 4) to determine the total volume in cups. This step-by-step process is a basic example of unit conversion and multiplication, ensuring that all the quantities are aligned correctly.

In real-life scenarios like cooking or grocery shopping, this type of conversion is common to adjust measurements based on different units of volume.
