Why do these two calculations not equal one another when the equation remains the same?

Question

Equation is 0.05*x*(x/y)

I have 3 sets of numbers (12, 5), (14, 6), and (25,10). These numbers are represented by (x,y) in the above equation.

Option 1: [0.05*12*(12/5)] + [0.05*14*(14/6)] + 0.05*25*(25/10)] = 6.198

Option 2: 0.05*(12+14+25)*[(12+14+25)/(5+6+10)] = 6.193

Why is there a difference in the result? Is there a term that explains this?

Answer 1

the term is...opshun 2 is gibberish or random fluke

me dont beleev it come in a lite-yeer av opshun1

bi the wae, hu sed yu kan add such numbrs??????

yer formula is x*x/20y

wi du yu wanna divide bi (12+14+25)????????????

or(5+6+10)????????????
