Lara puts pictures of the same size on each page in a scrapbook.

She has 48 large pictures, and each page can fit 3 large pictures.
She has 24 small pictures, and each page can fit 6 small pictures.
Which equation shows how to find p, the greatest number of pages Lara can fill in the scrapbook?

A.
48 ÷ 3 + 24 ÷ 6 = p
B.
48 ÷ 6 + 24 ÷ 3 = p
C.
48 × 3 + 24 × 6 = p
D.
48 ÷ 24 + 6 ÷ 3 = p

A. 48 ÷ 3 + 24 ÷ 6 = p

This equation represents dividing the total number of large pictures by the number that can fit on each page, and adding the result of dividing the total number of small pictures by the number that can fit on each page to find the greatest number of pages that Lara can fill in the scrapbook.
