# Feem pua suav tshuab xam zauv

### Dab tsi yog feem pua

Feem pua feem ntau txhais tau tias tus nqi txheeb ze los ntawm tag nrho cov nqi. Peb siv feem pua piv txwv li cov no:

1. Peb tag nrho cov nqi ntawm no yog ib lab lub tsheb.
2. Thiab peb hais tias: "txhua lub tsheb thib ob yog ntau dua tsib xyoos"
3. Txhais ua feem pua - "txhua lub tsheb thib ob" txhais tau tias tsib caug feem pua (50%).
4. Cov lus teb yog yog: ib nrab lab tsheb yog laus dua tsib xyoos.

Ib feem pua kuj txhais tau tias ib puas. Los ntawm cov piv txwv saum toj no - ib puas (1%) los ntawm lab yuav yog ib puas txhiab. $$x = \frac{1 000 000}{100} = 100 000 \\$$

#### Feem pua cov mis

$$Feem pua = Tus nqi / TotalValue \cdot 100 \\[1ex]$$
Piv txwv: Muaj pes tsawg feem pua yog 5 lub tsheb hauv 10 lub tsheb
$$Feem pua = (5 / 10) \cdot 100 \\ Feem pua = 50\%$$

#### Tus nqi mis

$$Tus nqi = Feem pua \cdot (TotalValue / 100) \\[1ex]$$
Piv txwv: Muaj pes tsawg lub tsheb yog 10% ntawm 50 lub tsheb
$$Tus nqi = 10 \cdot (50 / 100) \\ Tus nqi = 5 \, tsheb$$

#### Tag nrho tus nqi mis

$$TotalValue = Tus nqi \cdot (100 / Feem pua) \\[1ex]$$
Piv txwv li: TotalValue yog dab tsi 5 lub tsheb yog 50%
$$TotalValue = 5 \cdot (100 / 50) \\ TotalValue = 10\; tsheb$$
