Question

melissa plans to double the recipe for her favorite carrot cake in order to have enough for her grandmother’s 85th birthday party. the recipe calls for (\frac{1}{9}) cup of butter. use addition to find the number of cups of butter needed.
melissa needs (square) cup(s) of butter.
(simplify your answer. type a whole number, fraction, or mixed number.)

Explanation:

Step1: Understand the problem

Melissa is doubling the recipe, so we need to add the amount of butter in the original recipe twice. The original recipe has $\frac{1}{9}$ cup of butter.

Step2: Perform the addition

We need to calculate $\frac{1}{9}+\frac{1}{9}$. When adding fractions with the same denominator, we add the numerators and keep the denominator the same. So, $\frac{1 + 1}{9}=\frac{2}{9}$.

Answer:

$\frac{2}{9}$
