简单百分数问题

Answer 1

a. 妹妹得到的钱: 500*15% + 500*40%*25% =75+50 =125 (元) b. 弟弟余下的钱: 500*40%*(1-25%) = 500*40%*75% = 150 (元)
参考: 自己
哥哥比弟弟: 500x40%=200 哥哥比妹妹: 500x25%=125 弟弟比妹妹: 200x25%=50 妹妹最后得到: 125+50=175 弟弟最后余下: 200-50=150 总式： a)500x15%+500x40%x25% =500x15/100+500x40/100x25/100 =75+100 =175 b)500x40%x(1-25%) =500x40/100x75/100 =200x75/100 =150
a.哥哥给妹妹的钱 =500x15% =$75 哥哥给弟弟的钱 =500x40% =$200 弟弟给妹妹的钱 =200x25% =$50 妹妹最后得到 =75+50 =$125 b.哥哥给弟弟的钱 =500x40% =$200 弟弟给妹妹的钱 =200x25% =$50 弟弟最后余下 =200-50 =$150
哥哥给弟弟有款: 500 x 40% = 200元 哥哥给妹妹有款: 500 x 15% = 75元 弟弟分给妹妹: 200 x 25% = 50元 a:妹妹最后得:75 + 50 = 125元 b:弟弟最后余:200 - 50 = 150元
a:妹妹最后得到: 500*15% 500*40*25% =75 200*25% =75 50 =125(元) b:弟弟最后余下: 500*40%*(1-25%) =200*75% =150(元)
参考: ME
a:妹妹最后得到多少元? 500*15%+500*40*25% =75+200*25% =75+50 =125(元) b:弟弟最后余下多少元? 500*40%*(1-25%) =200*75% =150(元)
firstly $500 X 40% -->弟弟= $200 $500 X 15% -->妹妹= $75 secondly 弟弟把$200 --> $200 X 25%妹妹也就是$50 lastly 弟弟有$200-$50=$150 妹妹有$75+$50=$125
参考: myself
首先我地先计左弟弟先 弟弟最后余下: 500×40%×(1-25%) =200×75% =$150 然后再计妹妹 妹妹最后得到: 500×15%+150×25% =75+37.5 =$112.5
