Answer 1

276 acres in the forest.

Explanation:

Total area of the forest = 69000 acres

Old — grown trees = 0.4%

0.4% of 69000 = 69000× 0.4/100

= 69000×0.004= 276

Old grown trees are covered 276 acres in the forest.

Answer 2

`276` acres of old-growth trees are there.

Explanation:

Given: A forest covers
`69,000` acres. A survey finds that
`0.4\%` of the forest is​ old-growth trees.

To find: How many acres of​ old-growth trees are​ there?

Solution:

We have,

A forest covers
`69,000` acres.

Now,
`0.4\%` of the forest covers old-growth trees.

So, old-growth trees covers
`=0.4\%` of
`69,000`.

`=(0.4)/(100) *69,000`

`=(4)/(1000) * 69,000`

`=276`

Hence,
`276` acres of old-growth trees are there.
