Sol. 1 )
=> 11/19 of cup is filled
=> 1 - 11/19 of cup is empty
=> 1 - 11/19 = (19-11)/19 = 8/19
=> 9/19 of the cup is empty
Sol. 2)
=> 72 sweets
=> 1/4 with her
=> 1 - 1/4 = 3/4 shared
=> 3/4 of 72 is the number of sweets shared
=> 3/4 of 72 = (3*72)/4 = 3*18 = 54
=> She gave 54 sweets to her friends
Sol. 3)
=> 3/5 of 75 page of his lesson is read
=> 1 - 3/5 = 2/5 of 75 pages is left
