The museum wants to display all the art pieces in rows. each row has the same number of pieces and the same type of pieces. how many pieces could be in each row?

Each row can have 3 art pieces.

Step-by-step explanation:

We know that there are 30 oil paintings, 24 photographs and 21 sketches that a museum wants to display.

The arrangement of all these art pieces must be in rows such that each row has the same number and same type of art piece displayed.

If we observe, we can see that each of the numbers of the art pieces (including oil paintings, photographs and the sketches) have a greatest common factor which is 3.

Therefore, 3 art pieces can be displayed in each of the rows.
