Jill and rick had a total of 90 stickers at first. Jill lost 1/4 of her stickers to rick. In the 2nd game, rick lost 2/5 of his stickers to jill. As a result, the two children have the same number of stickers now. How many stickers did they have at first ?
it will be good if anyone can help to solve using fraction method or ratio method. Models definitely welcome. Thanks!
