Dale has a special deck of cards. each card has a different rational number on it. the cards are .25, 4/5, 2/9, 0.48 and 8/11. how many cards have a value that is greater than 1/2?

White shapes and black shapes are used in a game. some of the shapes are circles. while the rest are squares. the ratio of the number of white shapes to the number of black shapes is 5: 11. the ratio of the number of white cicrles to the number of white squares is 3: 7. the ratio of the number of black circles to the number of black squres is 3: 8. work out what fraction of all the shapes are circles.
