Piv txwv tias n yog tus lej. ∴ Reciprocal tus lej ntawd yog 1n. ∴ Reciprocal ntawm - 23 =1(− 23 ) =−32.
Kuj tseem paub yog, dab tsi yog qhov sib cuam tshuam ntawm 2/3 raws li ib feem?
Piv txwv tias n yog tus lej. ∴ Reciprocal tus lej ntawd yog 1n. ∴ Reciprocal ntawm - 23 =1(− 23 ) =−32.
Ib yam li ntawd, koj ua li cas thiaj nrhiav tau ib qho kev sib raug zoo? Lub ntsiab txhais ntawm " kev sib raug zoo "yog yooj yim. To nrhiav tus kev sib raug zoo ntawm ib tus lej, tsuas yog xam "1 ÷ (tus lej ntawd). Rau ib feem, cov kev sib raug zoo tsuas yog ib feem sib txawv, nrog cov lej "flipped" upside down (inverted). Piv txwv li, lub kev sib raug zoo ntawm 3/4 yog 4/3. Txhua lub sij hawm nws kev sib raug zoo yuav muab rau koj 1.
Yog li ntawd, dab tsi yog cov khoom ntawm 2/3 thiab nws cov reciprocal?
Cov khoom ntawm tus lej thiab nws reciprocal sib npaug 1. Cov kev sib raug zoo ntawm 2/3 yog 3/2. Tus lej 0 tsis muaj a kev sib raug zoo vim cov khoom ntawm ib tus lej thiab 0 sib npaug 0. Cov reciprocals ntawm ib tug lej qee zaum hu ua Multiplicative Inverse ntawm tus lej.
Dab tsi yog qhov sib txawv ntawm 2/3 8 hauv daim ntawv feem?
Tus denominator yuav nyob tib yam. Yog li, qhov tsis tsim nyog feem rau 2 3/8 yog 19/8. Tam sim no, tig 19/8 rau hauv a kev sib raug zoo . 19/8 ib kev sib raug zoo yuav yog 8/19.
