5. Start by finding how many tiles make up the outer edge of the pool. We know that each tile is 3/4 foot, and that the entire length is 12 feet. So by doing a division, we'll find how many tiles there are: 12 ÷ 3/4 = 16. By looking at the picture, we can confirm this. By looking at the picture we also see that the pool is the same length as 14 tiles, so the fraction is 14/16 -> 7/8.
I'm am going to suppose that it asks how many tiles are (touching) the pool and to not count the extra outer ones, and if that's the case, then the answer is 14/16 or 7/8. [also i think #6 is right] IF IT NEEDS TO KNOW THE LENGTH, THEN IT IS 10.5 (as a decimal).
