Question

You have 6 pounds of spaghetti. Each time you make dinner you use 2/3 of a pound of spaghetti. How many dinner can you make

Answer 1

When working with fractions it's always easiest if all the numbers have the same denominator. So let's start there.

`(2)/(3)` lb each night and
`6` lb total. We can make
`6` a fraction like this
`(18)/(3)`

Now we divide the total amount of spaghetti by how much we use each night. This will give us the number of dinners.

Explanation:

`((18)/(3))/((2)/(3)) = (18)/(3) * (3)/(2) = (18)/(2) = 9` dinners
