3 cups of flour are needed for each batch of oatmeal cookies.

Finding the measurement of flour for oatmeal cookies  

3 batches of chocolate chip cookies & 3 batches of oatmeal cookies are made from 12 3/4 cups of flour \; one batch of choco chip cookies use 2 1/4 cups of flour.

  • Flour needed for oatmeal cookies + flour needed for choco-chip cookies = Total cups needed = 12 3/4
  • Per batch flour needed for oatmeal cookies (Batch of oatmeal cookies) + Per batch flour needed for choco chip cookies (Batch of choco chip cookies) = 12 3/4

Let the per batch flour needed for oatmeal cookies = x

So Equation : 3x + 3 (2 1/4) = 12 3/4 3x + 3 (9/4) = 51/4 3x = 51/4 - 27/4 3x = 24 / 4 = 6 x = 6/3 = 2
