Isabella has 42 photos of her family. she has half as many photos of her friends. the photo album holds 4 photos on each page. how many pages will isabella need for all of her photos combined.

First, ignore the part about her friends because its not asking about that. Then divide 42 by 4 to get 10.5 and round to 11. So she will need a total of 11 pages to fit her photos.

Since 42 divided by 2 is 21, that's the number of pictures of friends. 42 plus 21 equals 63. To find out the number of pages she needs, divide the total (63) by how many photos each page holds (4). The final answer is 15.75. Although we are left with a decimal, we can round it to the answer 16.
