Final answer:
To determine how many photos the Advocacy Project for Homeless Pets classroom took, the number of photos (254) from the Saving Honeybees project must be multiplied by 15, resulting in a total of 3810 photos.
Step-by-step explanation:
The student is asking a math question involving multiplication. To find the total number of photos taken by the classroom working on the Advocacy Project for Homeless Pets, you need to multiply the number of photos taken by one classroom by 15. The first classroom took 254 photos. Therefore, the calculation would be:
254 photos × 15 = 3810 photos.
Thus, the classroom working on the Advocacy Project for Homeless Pets took 3810 photos.
