Answer 1

The difference of population of Germany and brazil

< The Difference of population of US and Brazil

< The Sum of population of Germany and brazil

< The Sum of population of US and Brazil

Explanation:

Make all population with equal power of 10

The difference of population of Germany and brazil

8.0 x 10^7 = 0.8 x 10^8

1.96 x 10^8

1.96 x 10^8 - 0.8 x 10^8

(1.96 - 0.8) x 10^8

1.16 x 10^8

Sum of population of US and Brazil

3.16 x 10^8

1.96 x 10^8

(3.16 + 1.96) x 10^8

5.12 x 10^8

Difference of population of US and Brazil

3.16 x 10^8

1.96 x 10^8

(3.16 - 1.96) x 10^8

1.2 x 10^8

The Sum of population of Germany and brazil

1.96 x 10^8

1.96 x 10^8 - 0.8 x 10^8

(1.96 + 0.8) x 10^8

2.76 x 10^8

So now arrange them in ascending order

1. The difference of population of Germany and brazil
2. The Difference of population of US and Brazil
3. The Sum of population of Germany and brazil
4. The Sum of population of US and Brazil
