Chapter 4, Problem 3STP

To determine

To calculate:Tofind how many batches one can make if one has $12\frac{1}{2}$ cups of flour.

Answer to Problem 3STP

  $5$ batches of recipe can be made

Explanation of Solution

Given information:Recipe of one batch of chocolate chip cookies is as follows:

Calculation:

Amount of flour one has $=12\frac{1}{2}$

  $=\frac{25}{2}$ cups

One batch of recipe require amount of flour $=2\frac{1}{2}$

  $=\frac{5}{2}$ cups

Thus, number of batches of recipe that can be made is calculated as follows:

  $\begin{array}{l}Number=\frac{\raisebox{1ex}{$25$}\!\left/ \!\raisebox{-1ex}{$2$}\right.}{\raisebox{1ex}{$5$}\!\left/ \!\raisebox{-1ex}{$2$}\right.}\\ Number=\frac{25}{2}\times \frac{2}{5}\\ Number=\frac{5}{1}\times \frac{1}{1}\\ Number=5\end{array}$

Hence, $5$ batches of recipe can be made
