It sounds like you are asking which is smaller
1/4 or 36.
1/4 is smaller than 1 (it means one-fourth, imagine taking a Pizza and dividing it into 4 equal pieces, then you taking one piece, you just took 1/4 of the pizza.)
While 36 means you ate 36 entire pizzas.
So, obviously 1/4 of a pizza is smaller than 36 whole pizzas so
1/4 is smaller.
1/9 - 1/4 = 4/36 - 9/36 = -5/36
40 over 36 is 1 and 1 over 9.
28/36 - 27/36 = 1/36
36/9 = 4/1 = 4
4/36 = 1/9
4/9 + 3/4 = 16/36 + 27/36 = 43/36 = 1 7/36
36/4 = 9/1
4/36 = 1/9
1/36
4 over 36 as a fraction in lowest terms is 1/9
36/28 or 1 8/36 which simplifies to 1 2/9
45
