Kimberly uses 1 cup of walnuts for every 2 cups of raisins when making trail mix. How many cups of walnuts will she need if she uses 8 cups of raisins.
Set this up as a ratio:
for every 1 cup of walnuts, she needs 2 cups of raisings :
1/2
so now how much cups of walnut does she need for 8 cups of raising
1/2 = x / 8
solve for x
The answer is
4cups/8cups
Or 4 for 8
the answer is:
4 cups
4 cups
To find out how many cups of walnuts Kimberly will need when using 8 cups of raisins, we need to use the ratio between the amount of walnuts and the amount of raisins.
According to the given information, Kimberly uses 1 cup of walnuts for every 2 cups of raisins. This can be written as the ratio: 1:2 (1 cup of walnuts to 2 cups of raisins).
To determine the number of cups of walnuts needed when using 8 cups of raisins, we can set up a proportion:
1 cup of walnuts / 2 cups of raisins = x cups of walnuts / 8 cups of raisins
To solve for x, we can cross-multiply and then divide:
2 cups of raisins * x cups of walnuts = 1 cup of walnuts * 8 cups of raisins
2x = 8
Divide both sides of the equation by 2:
x = 4
Therefore, Kimberly will need 4 cups of walnuts if she uses 8 cups of raisins to make trail mix.
