I need to work out fertiliser for spray the problem is as fallows

dry fertiliser all parts in % of weight

three parts A-B-C

1. Has. 15-20-17
2. Has. 0-54-32
3. Has. 0-0-60

l need final salutation of 200 letters with A at 100ppm. B at 650ppm and C at 650 ppm

I would be great full if you don’t give the answer but show me haw to calculate so I can do my own calculations for different % and ppm
