In a forest 4/7 of all the trees are conifer and the rest are leaf-bearing. Among the leaf-bearing trees 7/15 are oak and 2/3 of
these oaks are new. There are 160 old oaks in the forest. How many trees in all are in the forest?
1 answer:
(3/7) and (7/15) are oak.
(2/3)(7/15)(3/7)T are new oaks
(1/3)(7/15)(3/7)T are old oaks
------
(1/3)(7/15)(3/7)T = 160
(1/15)T = 160
I believe 160 x 15 - 2,400.
My best guess is there are 2,400 trees in the forest.
