Answer:
When working with fractions it's always easiest if all the numbers have the same denominator. So let's start there.
[tex]\frac{2}{3}[/tex] lb each night and [tex]6[/tex] lb total. We can make [tex]6[/tex] a fraction like this [tex]\frac{18}{3}[/tex]
Now we divide the total amount of spaghetti by how much we use each night. This will give us the number of dinners.
Step-by-step explanation:
[tex]\frac{\frac{18}{3}}{\frac{2}{3}} = \frac{18}{3} * \frac{3}{2} = \frac{18}{2} = 9[/tex] dinners
