2 / 3 4/6, 6/9, 8/12, 10/15, 12/18, 14/21, 16/24, 18/27, 20/30, 40/60, 80/120, 120/180, 160 /240, 200/300, 2000/3000 Koj tig 2.5 feem pua ua li cas feem ?
Yog li ntawd, dab tsi yog qhov sib npaug rau 23?
Sib npaug feem ntawm ib tug muab feem Nws tau txais los ntawm kev sib faib lossis faib nws tus lej thiab tus lej los ntawm tib tus lej. Piv txwv li, yog tias peb muab tus lej thiab tus lej ntawm 2/3 by4 peb. 2/3 luas = 2 x 4/3 x 4 = 8/12 sib npaug feem ntawm 2/3.
Tom qab ntawd, lo lus nug yog, dab tsi yog 3 hom feem? Hom Fractions
- Peb hom fractions yog:
- Muaj feem tsawg.
- Cov feem tsis raug.
- Mixed feem.
- Cov feem zoo: Cov feem uas nws cov zauv tsawg dua cov zauv yog hu ua cov feem zoo. (Tus lej < denominator)
- Piv txwv li:
Kuj tseem paub yog, dab tsi yog peb feem uas sib npaug rau 3 5?
Sib npaug Fractions Chart
| Ib feem | Fraction Equivalents | |
|---|---|---|
| 2/5 | 4/10 | 6/15 |
| 3/5 | 6/10 | 9/15 |
| 4/5 | 8/10 | 12/15 |
| 1/6 | 2/12 | 3/18 |
Yuav ua li cas koj ua cov feem sib npaug?
Cov ntsiab lus:
- Koj tuaj yeem ua cov feem sib npaug los ntawm kev sib faib lossis faib ob sab saum toj thiab hauv qab los ntawm tib tus nqi.
- Koj tsuas yog muab faib lossis faib, tsis txhob ntxiv lossis rho tawm, kom tau ib feem sib npaug.
- Tsuas yog faib thaum sab saum toj thiab hauv qab nyob raws li tus lej tag nrho.

Yuav daws qhov tsis sib npaug ntawm cov kab sib npaug thiab cov kab sib npaug sib npaug li cas?
Kev daws qhov tsis sib npaug ntawm qhov sib npaug yog zoo ib yam li kev daws cov kab sib npaug. Qhov sib txawv tseem ceeb yog koj tig lub cim tsis sib xws thaum faib lossis muab faib los ntawm tus lej tsis zoo. Graphing linear inequalities muaj ob peb qhov sib txawv ntxiv. Qhov uas yog qhov ntxoov ntxoo muaj xws li qhov tseem ceeb uas qhov kev tsis sib xws ntawm cov kab tawm muaj tseeb
Qhov sib npaug sib npaug rau qhov nruab nrab ntawm h2so4 los ntawm Koh yog dab tsi?
Hauv daim vis dis aus no peb yuav sib npaug ntawm qhov sib npaug KOH + H2SO4 = K2SO4 + H2O thiab muab cov coefficients raug rau txhua qhov sib xyaw. Txhawm rau sib npaug KOH + H2SO4 = K2SO4 + H2O koj yuav tsum nco ntsoov suav tag nrho cov atoms ntawm txhua sab ntawm cov tshuaj sib npaug
Dab tsi sawv cev rau qhov sib npaug ntawm kev sib npaug nuclear?
Ib qho kev sib npaug nuclear sib npaug yog ib qho uas cov lej ntawm cov lej loj (tus lej saum toj kawg nkaus hauv cov cim) thiab cov lej ntawm cov lej atomic sib npaug ntawm ob sab ntawm qhov sib npaug. Nuclear equation teeb meem feem ntau yuav muab xws li tias ib qho particle ploj lawm
Puas yog txhua qhov sib npaug sib npaug sib npaug?
Thawj qhov sib npaug sib npaug yog qhov tseeb yog tias nws muaj kev txuag kom muaj nuj nqis. Piv txwv li, qhov sib npaug sib cais yeej ib txwm muaj tseeb, txij li lub ntsiab lus lawv yog ntawm daim ntawv: M(y) + N(t) = 0, yog li ϕ(t, y) = A(y) + B(t) yog a khaws cia kom muaj nuj nqis
Dab tsi yog qhov sib txawv ntawm cov kab lus sib npaug thiab qhov sib npaug sib npaug?
Cov kab lus sib npaug muaj qhov muaj txiaj ntsig zoo ib yam tab sis tau nthuav tawm nyob rau hauv ib hom ntawv sib txawv uas siv cov khoom ntawm cov lej xws li ax + bx = (a + b) x yog cov kab lus sib npaug. nruj me ntsis, lawv tsis yog 'sib npaug', yog li peb yuav tsum siv 3 kab sib luag hauv 'sib npaug' es tsis yog 2 raws li qhia ntawm no
