+12 Our badminton team has finished $75\%$ of its season. So far, we have won $45\%$ of the games we played. What percent of the remainder of our games must we win in order to finish the season with the same number of wins as losses?
Since 75% of the season has been completed, 25% of the season remains. Thus, we have 25 games left to play.
We must win 55% of the remaining games in order to have a 50-50 win-loss record. To find this, we convert the percentage to a decimal and divide by 4: 55%=55/100=11/20. So, we must win 44% of the remainder of our games in order to finish with a 50-50 win-loss record.
+129845 Let G be the total number of games you play
Let .75 G be the number of games you have played
Let . 45 (.75)G be the number of games you have won
Let .25G be the games left
Let .50G = the number of wins you must have
And number of wins you need - Number of wins you have = No. of wins you need in your remaining schedule
So
[ No. of wins you need - No, of wins you have ] / [ No. of Games Left ]
[ .50G - .45 (.75)G ] / .25G =
(.1625 G ) / ( .25G) = .65 (you need to win 65% of your remaining games )
