100% + 1.8% = 101.8%
101.8% = 101.8/100 = 1.018
1) 450 * 1.018 = 458.10 in one month
2) 458,1 * 1.018 ≈ 466.35 in two months
3) 466,35 * 1.018 ≈ 474.74 in three months
4) 474,74 * 1.018 ≈ 483.29 in four months

You know you need to rename a mixed number to subtract when the numbers involved have different denominators. In such a case. The lowest common multiple of the denominators will be calculated subsequent used to adequately rename the mixed numbers before subtraction can be done
8000-4.989 so when you see the word less than it means that you have to subtract and more than you have to add so the answer for this question will be 7,995.011
The point (a,b) would be in quadrant 2 (the one on the top left)
