Depends on what you mean. If it's like 6 apples, 8 oranges, and 3 bananas find the percentage of fruits that are apples/bananas/oranges, you just do this (assume you round to the nearest percent)
(apples/total fruit)x100 (oranges/total fruit)x100 (bananas/total fruit)x100
(6/17)x100 (8/17)x100 (3/17)x100
(.3529...)x100 (.4705...)x100 (.1764...)x100
35.29...% 47.05...% 17.64...%
35% 47% 18%
35% of the fruits are apples. 47% of the fruits are oranges 18% of the fruits are bananas
