Question

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

Answer 1

Hint: First of all, we should know how many ounces of fluid contained in 4 jars. For that, we know that one jar contains 26 ounces of spaghetti sauce so the ounces that 4 jars contain are calculated by multiplying 26 by 4. Now, the number of cups of spaghetti sauce that 4 jars contain is calculated by dividing the total ounce that 4 jars contain by the number of ounces that one cup contains. And we know that one cup contains 8 ounces of fluid.

Complete step by step answer:
It is given that a jar contains 26 ounces of spaghetti sauce. So, the fluid that 4 jars contain is calculated by multiplying 26 by 4 and we get,
 $\begin{array}{rl}& 26\times 4\\ & =104\end{array}$
From the above calculations, we got 104 ounces of spaghetti sauce in 4 jars.
Now, in the above problem we are asked to find the number of cups of spaghetti sauce contain in 4 jars. For that, we should know how many ounces of fluid that a cup contained. We know that a cup contains 8 ounces of fluid so to calculate the number of cups of spaghetti sauce we are going to divide 104 ounces by 8 and we get,
 $\begin{array}{rl}& {\displaystyle \frac{104}{8}}\\ & =13\end{array}$
From the above calculations, we have found that 4 jars contain 13 cups of spaghetti sauce.

Note:
To solve the above problem, you must know how many ounces of fluid a cup can contain. If you don’t know this information then you will stick at the place when we have calculated the total fluid that can be contained in 4 jars.
The other mistake that could be possible in the above solution is the calculation mistake so make sure you have carefully done the multiplication and division.
