Turner's Cafe uses 1 5/8 bags of coffee every day. How many days will 6 1/2 bags of coffee last?

Answer 1

Hello Bob,

One way you could approach this is dividing 6 1/2 by 1 5/8. Let's convert both mixed numbers into improper fractions:

6 1/2 --> 13/2

1 5/8 --> 13/8

Now - divide 13/2 by 13/8 ---> (13/2) / (13/8) = (13/2) * (8/13)

The "13" at the numerator and the "13" at the denominator cancel out, so you're left with 8/2 which equals exactly 4.

So (13/2) / (13/8) = 4.

6 1/2 bags of coffee will last 4 days.
