kim finds a 5 - meter tree branch and marks it off in thirds and fifths . she then breaks the branch along all the markings and removes one piece of every distinct length . what fraction of the original branch remains ?
a ) 8 / 15 , b ) 1 / 2 , c ) 7 / 5 , d ) 3 / 5 , e ) 7 / 5
Choose the correct option letter a-e.
| the fractional parts are 1 / 5 , 1 / 3 , 2 / 5 , 1 / 5 , and 2 / 5 . one of each is removed , and their sum is 1 / 5 + 1 / 3 + 2 / 5 + 1 / 5 + 2 / 5 = 12 / 15 , so 1 - 12 / 15 = 3 / 15 of the branch remains . the answer is d .
Final answer: d | the distinct markings will be 1 / 5 , 1 / 3 , 2 / 5 and 2 / 3 . these will give pieces of these lengths when the branch is broken . one of each is removed . the total length of the removed pieces is 1 / 5 + 1 / 3 + 2 / 5 + 2 / 3 = 14 / 15 . this is removed from the original branch . therefore 1 / 15 of the branch remai... |

Final answer: d | 5 / 3 = 2.5 and 5 / 5 = 1 so the markings are at 1, 1.25, 1.5, 1.75, 2, 2.5 . this gives us 1 , 0.25 , 0.5 , 0.75 , 1 , 0.5 , 0.5 , 0.25 , 1 . sum of the distinct lengths is 1 + 0.5 + 0.25 = 1.75 = 7 / 4 . fraction that remains is 1 - 7 / 4 = 7 / 5 . answer e .
