To find the rate of boxes of spaghetti to the number of ounces, you can set up the following ratio:
\[ \frac{\text{Number of boxes}}{\text{Weight in ounces}} = \frac{14 \text{ boxes}}{168 \text{ ounces}} \]
To simplify this ratio, divide both the numerator and the denominator by the greatest common divisor (GCD) of 14 and 168.
The GCD of 14 and 168 is 14.
Now, divide both parts by 14:
\[ \frac{14 \div 14}{168 \div 14} = \frac{1}{12} \]
Therefore, the rate of boxes of spaghetti to the number of ounces is:
\[ 1 \text{ box} : 12 \text{ ounces} \]
This means that for every 1 box of spaghetti, there are 12 ounces.
