（3）男隊(duì)員比女隊(duì)員少

（4）女隊(duì)員比男隊(duì)員少

Answer 1

【答案】

【解析】

（1）女隊(duì)員比男隊(duì)員多，男隊(duì)員人數(shù)是單位“1”，求女隊(duì)員人數(shù)要先求出女隊(duì)員對應(yīng)百分率，用男隊(duì)員人數(shù)×女隊(duì)員對應(yīng)百分率；

（2）男隊(duì)員是女隊(duì)員的，女隊(duì)員人數(shù)是單位“1”，用男隊(duì)員人數(shù)÷男隊(duì)員對應(yīng)百分率即可；

（3）男隊(duì)員比女隊(duì)員少，女隊(duì)員人數(shù)是單位“1”，根據(jù)女隊(duì)員人數(shù)×男隊(duì)員對應(yīng)百分率＝男隊(duì)員人數(shù)，列方程即可；

（4）女隊(duì)員比男隊(duì)員少，男隊(duì)員人數(shù)是單位“1”，先求出女隊(duì)員對應(yīng)百分率，用男隊(duì)員人數(shù)×女隊(duì)員對應(yīng)百分率。
