Let&#039;s denote the number of cookies needed as x.We have the following proportion:4515=x30To solve for x, we can cross-multiply:45·30=15xNow, we can solve for x by dividing both sides of the equation by 15:x=45·3015Simplifying the expression:x=135015x=90Therefore, 90 cookies are needed for 30 students.

Step 1:We can set up the proportion as follows:4515=x30Here, the fraction on the left side represents the ratio of cookies to students for the initial scenario, and the fraction on the right side represents the ratio for the desired scenario.To solve for x, we can cross-multiply and then divide:45×30=15×xStep 2:Now we can solve for x:x=45×3015Simplifying the expression on the right side:x=135015Finally, performing the division:x=90Therefore, we need 90 cookies for 30 students.
