Question

The area of Chile is 291,930 square miles. The area of Mexico is 761,606 square miles.

Answer 1

First, we are going to identify what information we have and what is unknown:
Chile's area=291,930
Mexico's area=761,606
Unknown= How much larger Mexico is than Chile.
Next we will write an equation showing Mexico's area minus Chile's area:
761606-291930
Then we will solve and get a difference of:
469,676
Now you know the exact number, so now we need to round to the nearest thousand to find a rounded answer.
761606 rounds to 762,000
291930 rounds to 292,000
762,000-292,000=470,000
470,000 is close to 469,676.
Therefore, Mexico is about 470,000 square miles larger than Chile.
