you would know because for example, if it's out of 4 and the fraction said 4/4, that would mean one. 3/3 would mean one. 2/2 and so on
pegah
2/2 = 1  and (1/3)^0 = 1  so x/x = 1 because there is same number and (x/y)^0= 1 because its 0 and 1/1 is always 1 these are the fractions that are always 1 :))
i hope this be helpful 
have a nice day
