To find the answer you have to find a common factor of 55 and 88. The most obvious one is 11. 55/11=5 and 88/11=8. Because there is not a common factor between 5 and 8, 55 is now 5 and 88 is now 8. So your simplest form is 5 over 8.
A/88 is already in simplest form, unless you know the value of A.
88/317 is in simplest form.
49/88 is already in simplest form.
88
That is in simplest form...
88/88 = 1
88/89 is already in its simplest form
40/88 is 5/11 in its simplest form
8/88 = 1/11
It is: 24/88 = 3/11
It is: 88/66 = 4/3
