A photo that is 8 in. wide and 12 in. long is enlarged to a poster. If the width is enlarged to 24 in., what is the length of the poster?
24 x 4 = 48/12 = 4
right....????

No. That answer doesn't make any sense. The length must be a lot longer than 12 in.

12 x 8 = 96/24 = 4

why can you just multiply 3/4 and 10 to get the answer?
why 3/4 * 8 = 24/4 = 6...??

Because you've reduced the size to 3/4 of its original size.
