Jenny is displaying her photographs
on a table at a sidewalk art show. she
has 45 photos of people, 18 photos
of landscapes, and 63 photos of pets.
each row will have the same number
of photos, but people, landscapes, and
pets will not appear in the same row. if
she puts the greatest possible number of
photos in each row, how many rows will
there be?

A) 9 photos in each row

B) 14 rows in total

Step-by-step explanation:

Photos of People = 45

Photos of Landscapes = 18

Photos of Pets = 63

Jenny wants to arrange these photos in rows with only one kind of photos in each row and same number of photos in each row. We have to find the greatest possible number of photos in each row. For this we need to find the greatest common factor of 45,18 and 63. This would give us the greatest possible number of photos that can be placed in each row.

By observing the 3 numbers, we can tell that the greatest common factor of these 3 numbers is 9. So, Jenny can place 9 photos in each row.

So,

There will be:

45/9 = 5 rows with photos of people

18/9 = 2 rows of photos of landscapes

63/9 = 7 rows of photos of pets

So, total number of rows would be = 5 + 2 + 7 = 14 rows

it should be a and d. lmk if i'm wrong xd
