Here we know that for cookies we need 3 eggs and 0.5 cups of butter.

The ratio of eggs to butter = \(\frac{3}{0.5}\).

Now she has 2 eggs and let the cups of butter required be x.

For ratio of eggs to butter to be same we know that.

\(\frac{3}{0.5}\)=\(\frac{2}{x}\).

Hence \(x=\frac{1}{3}\).

We can solve the question by using equivalent ratios

We're comparing eggs to butter (and flour and sugar, but that information isn't needed)

We require 3 eggs for every 0.5 cups of butter.

We have 2 eggs and we need to determine the amount of butter

Let x = the number of cups of butter needed with 2 eggs

We get: 3/0.5 = 2/x
Cross multiply to get: (3)(x) = (0.5)(2)
Simplify: 3x = 1
Solve: x = 1/3

Answer: 1/3
