I need some help on problems like 10,560 ft. = ___ miles. Also, I
don't know how much a mile is in yards, feet, and inches. I need major
help.

Hi, Courtney.

Just remember one fact about miles: a mile is 5280 feet.

Now suppose you have 10,560 feet. Picture that as 10,560 foot rulers.
If you can get 5280 of them together in one stack, that will be a
mile. How many of these stacks can you make? You divide, and get ...

Similarly, suppose you want to know how many yards there are in a
mile. You have 5280 rulers in a stack. For every three of these you
can put together, you will have a yard. So how many groups of three
can you make out of those 5280?

Again, you divide, this time 5280 by 3.

Finally, how can you find the number of inches in a mile? Again, we
start with those 5280 rulers. This time we chop each one into twelve
pieces, each an inch long. How many will you have? Every ruler is
replaced by twelve pieces, so there are 12 times 5280 inches in a
mile.

If you need more help, write back and show me a problem you have
trouble with, together with your work, so I can see where you need
help.
