A forest covers 33,000 acres. A survey finds that 0.8% of a forest is old-growth-tree. How many acres of old-growth-trees are there?

Answer:

264 acres

Step-by-step explanation:

Since 33,000 acres is 100%, 330 acres is 1% because 33000 acres divided by 100 is 330 acres. Then if 330 acres is 1%, 33 acres is 0.1% because 330 acres divided by 10 is 33 acres. 1 divided by 10 is 0.1.

Next 33 acres times 8 because 0.8% is eight times bigger than 0.01%. This equals to 264 acres.
