The amount, in oz of butterscotch chips needed by proportional reasoning is; 75oz.
<h3>What is the amount of butterscotch chips needed by proportional reasoning?</h3>
It follows from the task content that the the amount of butterscotch chips needed can be determined by means of the proportion premise declared in which case;
- The recipe requires 3 times as many chocolate chips as butterscotch chips.
Hence, when 25oz of chocolate chips is used, the amount of butterscotch needed is 3 times 25 and hence, = 3 × 25 = 75oz.
