Well, the simplest way to do this is to do the cross-product method. First we have to have on one side x/79, and on the other side, 200/100. (Here's what it looks like when put properly) And for the cross product method, we multiply 79 by 200, which is 15800, and since we have that 100x, this is the new equation. (15800 = 100x) We divide 15800 by 100, and you get 158, So 200% of 79 is 158. I hope this helps you.
