1/4 of her tickets to her family and 3/8s to her friends, she had 30 tickets left
Since, 1/4 = 2/8 , she has given away, ( (2/8) + (3/8) = 5/8 ), 5/8ths of her tickets.
That means that the remaining 30 tickets are 3/8ths of the original number of tickets.
So if , 30 tickets = 3/8
Then , 1/8 = 10 tickets
So she originally had 80 tickets.
