Q. Lila is making oatmeal cookies for the Charlestown Community Bake Sale. Lila sets aside 1781\frac{7}{8} pounds of the cookie dough to remain plain, and then she adds raisins and walnuts to the rest of the dough. Lila makes 1515 equal-sized cookies with the plain cookie dough. How much plain cookie dough does she use for each cookie? Use the model to help answer the question. Write your answer as a whole number, proper fraction, or mixed number. \newline____ pounds
  1. Convert to Improper Fraction: Convert 1781\frac{7}{8} to an improper fraction for easier calculation. 178=(1×8+7)/8=1581\frac{7}{8} = (1\times8 + 7)/8 = \frac{15}{8}
  2. Calculate Amount per Cookie: Divide the total amount of plain cookie dough by the number of cookies to find the amount per cookie. 158÷15=158×115=18\frac{15}{8} \div 15 = \frac{15}{8} \times \frac{1}{15} = \frac{1}{8}
