Desiree is making guacamole for a party. The recipe she is using calls for 1/4 cup lime juice for every 4 avocados. If she plans to use 1 cup of lime juice, how many avocados does she need.

If the recipe calls for 1/4 cup of lime juice for every 4 avocados, then for 1 cup of lime juice, Desiree will need 1 cup * 4 avocados / (1/4 cup) = 4*4= <<1*4=4>>16 avocados. Answer: \boxed{16}.

To determine the number of avocados Desiree needs, we can set up a proportion using the given information:

1/4 cup lime juice is needed for every 4 avocados.

Let's assign the number of avocados needed as x.

So, the proportion becomes:

1/4 cup lime juice = x avocados

1 cup lime juice = 4 * x avocados

Now, we can solve for x by cross-multiplying:

1 * x = 1 cup lime juice * 4 avocados

x = 4 avocados

Therefore, Desiree needs 4 avocados for 1 cup of lime juice.

To find out how many avocados Desiree needs, we can set up a proportion using the given information.

Let's start by setting up the proportion with the number of avocados (x) she needs:

(1/4 cup lime juice) / (4 avocados) = (1 cup lime juice) / (x avocados)

Now we can cross-multiply and solve for x:

(x avocados) = (1 cup lime juice) * (4 avocados) / (1/4 cup lime juice)

Simplifying the expression:

(x avocados) = (1 cup lime juice) * (4 avocados) / (1/4 cup lime juice)
(x avocados) = (1 cup lime juice) * (4 avocados) / (1/4 cup lime juice)
(x avocados) = (1 * 4 avocados) / (1/4)
(x avocados) = 4 avocados * 4
(x avocados) = 16 avocados

Therefore, Desiree needs 16 avocados to make the guacamole.
