Okay so I've been stuck on question 6,7, and 8 for a while now and I cannot figure it out. I need help showing my work. I have to "Find the Pct to the nearest thousandth" the question #6 is "Games won---15; Games played---25" the answer is ".600", The question to #7 is "Games won---10;Games lost---15" I know the answer is ".400" and now for #8 it is "Games won---18; Games lost---18" the answer is ".500", again I just need help with showing my work if you can help me that would be great :)
15/25 = x/100
x = (100/25)15 = 4 * 15 = 60 %
7. games played = 10 + 15 = 25
percent won = 100 (10/25) = 4*10 = 40%
8. games played = 18+18
percent won = 100 * 18/(18+18) = 50 %
