Partial products are different because partial product you have 2 product when you add together gives you the answer and in regular multiplying it just straight gives you the answer without adding anything.Partial products is easier if you don't know your multiplying facts.They are similar because they both give you the same answer just using different ways of doing it
Hope this helped:-)
Let the following denote:
s = number of standard downloads
2s = number of high-quality downloads 2.6s + 4.4(2s) = 2622
2.6s + 8.8s = 2622
11.4s = 2622
s = 230
The standard version was copied 230 times and the high-grade type was downloaded 460 times.
-8,-3 if i read that correctly, that should be the answer.
