Answer: 76 pages
Explanation:
700 photo spaces = 100%
-The total
168 photo spaces = 24%
-The number of empty spaces in the album.
- Find 24% of 700:
70(10%) x 2 = 140
7(1%) x 4 = 28
140 + 28 = 168
532 photo spaces = 76%
- The number of photos in the album
700 - 168 = 532
Finding the number of pages.
-As we know 1 page holds 7 photos, if we had 532 photos we'd have to divide it by 7 to see how many pages all the photos would be held in.
532 ÷ 7 = 76.
