分析:(1)把男隊(duì)員的人數(shù)看成單位“1”,女隊(duì)員的人數(shù)是男隊(duì)員的(1+
),用男隊(duì)員的人數(shù)60人乘上(1+
),就是女隊(duì)員的人數(shù);
(2)把男隊(duì)員的人數(shù)看成單位“1”,女隊(duì)員的人數(shù)是男隊(duì)員的
,用男隊(duì)員的人數(shù)60人乘上
,就是女隊(duì)員的人數(shù);
(3)把女隊(duì)員的人數(shù)看成單位“1”,男隊(duì)員比女隊(duì)員少
,男隊(duì)員的人數(shù)就是女隊(duì)員的(1-
),它對(duì)應(yīng)的數(shù)量是60人,所以用60除以(1-
)就是女隊(duì)員的人數(shù);
