Your correct on both but you rounded your percent to the nearest hundredth instead of tenth.

So...

1. would be just 8.1

2. would be 6.6

First, get the knowns and unknowns on the your best option ingredient of the equivalent sign: a million. subtract 2. from the two aspects: 2x -2x +3 = 3x - 2x - 4 2. now you have: 3 = x -4 3. upload 4 to the two aspects : 3 + 4 + x -4 +4 4. now you have: 7 = x 5. practice: 2 (7) +3 = 3 (7) -4 or 14 +3 = 21 - 4 or 17 = 17

#1 - correct. Take Europe/World then multiply by 100.

#2 - correct also. Again, Europe/World, then x 100.

Correct both times except that second answer is just 6.56% you shouldn't have miles squared after it.

You are right!!!!!

510,000,000 divide by 6,279,000,000 then mult by 100 to give you a answer.

3,800 divide by 57,000 then mult by 100 to give you a answer.
