Answer:
2(2/5x+2)= 2*2/5x + 2*2= 4/5x+4
For this case we have the following expressions:
70,000,000
7,000,000
If we divide the first expression by the second we have:

Thus, we have that the first expression is 10 times greater than the second expression.
Answer:
70,000,000 is 10 times greater than 7,000,000
The anwser is 9.8333333333
