We are given that we need to measure 1/4 cup of flour with a measuring device that can only hold 1/8 cup.
To determine the 1/4 cup we need to have into account that:
[tex]\frac{1}{8}+\frac{1}{8}=\frac{2}{8}=\frac{1}{4}[/tex]Therefore, two times 1/8 is 1/4 therefore, Carter can fill the 1/8 cup two times to get 1/4 cup.
