For a, we have 42in/9ft. Since 12 inches are in 1 foot, we can multiply it by that to get (42in/9ft)*(1ft/12inches) = 42/108. We put the foot on the top of 1ft/12in to cancel them out. Since 2 goes into both 42 and 108, we divide it by 2/2 to get 26/54. Repeating the process again, we get 13/27
If we were to say that there are 12 inches in a foot and therefore divide 42 by 12 (to get 42 inches in feet), we'd get the same answer due to that 1 foot is equal to 12 inches and if you were to divide it by 1 foot/12 inches, since they are the same thing, you get the same answer
For c, since it may be hard to get (42/12)/9, it could just be easier to have 42/(9*12)=42/108

Answer:
A perfect square is an integer that results in another integer when square rooted.
Step-by-step explanation:
For example:
16 is a perfect square because 
= 4.
16 and 4 are both integers
Also, notice that 4 x 4 = 16
30 minutes is 1/2 an hour.
60 minutes is a full hour.
Monday thru Saturday is:
Monday, Tuesday, Wednesday, Thursday. Friday, Saturday. That is 6 days total.
30 minutes a day for 6 days is 180 minutes.
180 minutes / 60 minutes = 3 hours.
3 hours x $7 = $21
