Question

A forest covers 64,000 acres. A survey finds that 0.4​% of the forest is​ old-growth trees. How many acres of​ old-growth trees are​ there?

Answer 1

Total area of the forest = 64000 acres

Old — grown trees = 0.4%

0.4% of 64000 = 64000× 0.4/100

= 69000×0.004= 256

Old grown trees are covered 256 acres in the forest.

I’m not sure if that’s right but it’s my best answer
