Question

Diana uses 30 g of coffee beans to make 48 fluid ounces of coffee. We guess, she makes 96 fluid ounces coffee. How many grams of coffee does beans does Diana use when she has visitors?

Answer 1

60g

Explanation:

Okay, the first ratio we have is 30:48 (because she uses 30g of coffee beans to make 48 fluid oz).

To find how many coffee beans she uses for 96 fluid oz we need to find the unit rate.

To find the unit rate you divide the number by the greatest common factor of both numbers. The GCF of both numbers is 6 so we divide 30 and 48 by 6. We get the unit ratio of 5:8.

Now we can solve it.

We can solve the equation of
`(x)/(96) =(5)/(8)`.

To solve this equation we need to multiply 96 by
`(5)/(8)`. Doing this gives us our answer of 60.
