Sarah is making 4 batches of granola bars. She needs 7/8 cup peanuts to each batch and her measuring cup holds 1/8 cup.
Thus, if one cup holds [tex] \frac{1}{8} [/tex] then to make [tex] \frac{7}{8} [/tex], Sarah will have to measure [tex] \frac{7}{8} =7\times \frac{1}{8} [/tex]= 7 times for one batch of granola bars.
Therefore, for making 4 batches of granola bars, Sarah must measure 1/8 cup peanuts 7 x 4=28 times.
