That all depends upon the soil that you have to start with. NPK stands for, "nitrogen, phosphorous, pottassium". What you are proposing has only nitrogen, but no P or K. If you send a sample of your soil to the lab for analysis, and find out that it has plenty of P and K, but is low on nitrogen, then the ammonium sulfate might just be what you need. However, in the absence of a soil analysis, I would start with a more balanced fertilizer.
7% of 2100 = 7% * 2100 = 0.07 * 2100 = 147

There is no next number because numbers are infinitely dense. The next positive integer is 2100.
1/3 * 2100 = 2100/3 = 700
110% of 2100 = 2100*110/100 = 2310
