Personally I think the answer would be c. Cross multiplication
To solve this problem, we must remember our place values. 100,000 represents hundred thousands, 10,000 represents ten thousands, and 1,000 represents thousands similarly to how 100 represents hundreds, 10 represents tens, and 1 represents ones. Using this knowledge, we know that the number 8 is in the hundred thousands place, the number 0 is in the ten thousands place, and the number 1 is in the thousands place.
This means that there are 8 hundred thousands, 0 ten thousands, and 1 thousand in the number of acres of land the National Park owns.
Hope this helps!
