Have two types of fertilizers but want to get a new ratio - how to guide

Let's say I have a 5-1-0 and a 1-4-7, i want to get an a different ratio but am too cheap to go buy another fertilizer. What do I do? Mix the two.

I'll start by using 60% of 5-1-0 and 40% 1-4-7.

Take .6 x 5-1-0 = 3 - 0.6 - 0
Take 0.4 x 1-4-7 = 0.4 - 1.6 - 2.8

Add the two together gives you 3.4 - 2.2 - 2.8 for the resulting NPK

How about 10% 5-1-0 and 90% 1-4-7

0.1x 5-1-0 = 0.5 - 0.1 - 0
0.9 x 1-4-7 = 0.9 - 3.6 - 6.3

Sum is 1.4 - 3.7 - 6.3 is the resulting NPK

Yeah you could say that I like math too, lol, in university I got 99% on my calculus midterm years ago.

I currently have a spreadsheet on the go for making soil recipes from different online soil articles and working with an agronomist to verify. It's interesting the ideal ratios between certain elements, while others are not so important. All math, all the time, nerding right out and lovin it.

A little chemistry and biology come in handy too for growing weed, and that shit interests me also.
