Answer:
4,500 days, years, or months
Your income is $1000, and you are trying to get $4,500,000.
You can do this is by dividing $4,500,000 with $1000.
Division
4500000/1000
Cross out all the numbers of 1000 into 4500000 until you get 1.
Since there are 3 zeros in 1000, you cross 3 out in 4,500,000
So, your answer will be 4,500.
It will take 4,500 days, years, or months (You didn't say the unit)
