Final answer:
To find out how many photos each judge will review, divide the total number of photos by the number of judges.
Step-by-step explanation:
To find out how many photos each judge will review, we can divide the total number of photos by the number of judges. In this case, there are 1020 entries in the photo contest and 6 judges. So, to find out how many photos each judge will review, we divide 1020 by 6:
1020 ÷ 6 = 170
Each judge will review 170 photos.
