考點(diǎn):單位“1”的認(rèn)識(shí)及確定,分?jǐn)?shù)乘法應(yīng)用題
專題:分?jǐn)?shù)百分?jǐn)?shù)應(yīng)用題
分析:實(shí)際產(chǎn)量比計(jì)劃減少
,是把計(jì)劃產(chǎn)量看作單位“1”的量;實(shí)際比計(jì)劃少的產(chǎn)量占計(jì)劃產(chǎn)量的
;其數(shù)量關(guān)系式是:計(jì)劃產(chǎn)量×
=實(shí)際比計(jì)劃少的產(chǎn)量.實(shí)際產(chǎn)量占計(jì)劃產(chǎn)量的
,計(jì)劃產(chǎn)量×(1-
)=實(shí)際產(chǎn)量.
解答:
解:實(shí)際產(chǎn)量比計(jì)劃減少
,把計(jì)劃產(chǎn)量看作單位“1”的量,實(shí)際比計(jì)劃少的產(chǎn)量占計(jì)劃產(chǎn)量的
,計(jì)劃產(chǎn)量×
=實(shí)際比計(jì)劃少的產(chǎn)量.實(shí)際產(chǎn)量占計(jì)劃產(chǎn)量的
,計(jì)劃產(chǎn)量×(1-
)=實(shí)際產(chǎn)量.
故答案為:計(jì)劃產(chǎn)量,實(shí)際比計(jì)劃少的產(chǎn)量,計(jì)劃產(chǎn)量,計(jì)劃產(chǎn)量,實(shí)際比計(jì)劃少的產(chǎn)量,實(shí)際產(chǎn)量,計(jì)劃產(chǎn)量,計(jì)劃產(chǎn)量,實(shí)際產(chǎn)量.
點(diǎn)評(píng):此題主要是考查單位“1”的確定、分?jǐn)?shù)乘除法的應(yīng)用等.通常找單位“1”的方法是:和誰(shuí)比誰(shuí)是“1”,誰(shuí)的幾分之幾或百分之幾誰(shuí)是“1”.
