# Kubara Ijanisha

### Ijanisha ni iki

Ijanisha risobanura agaciro kagereranijwe uhereye ku giciro rusange. Dukoresha ijanisha kurugero nkuyu:

1. Agaciro kacu hano ni imodoka imwe.
2. Kandi turavuga tuti: "buri modoka ya kabiri irengeje imyaka itanu."
3. Byahinduwe ku ijanisha - "buri modoka ya kabiri" bisobanura mirongo itanu ku ijana (50%).
4. Igisubizo cyukuri ni: igice cya miliyoni yimodoka irarenze imyaka itanu.

Ijanisha rimwe risobanura kandi ijana. Duhereye kurugero rwo hejuru - ijana (1%) kuva miriyoni yaba ibihumbi ijana. $$x = \frac{1 000 000}{100} = 100 000 \\$$

#### Ijanisha

$$Ijanisha = Agaciro / Agaciro \cdot 100 \\[1ex]$$
Urugero: Ni bangahe ku ijana ni imodoka 5 kuri 10
$$Ijanisha = (5 / 10) \cdot 100 \\ Ijanisha = 50\%$$

#### Agaciro formulaire

$$Agaciro = Ijanisha \cdot (Agaciro / 100) \\[1ex]$$
Urugero: Imodoka zingahe ni 10% yimodoka 50
$$Agaciro = 10 \cdot (50 / 100) \\ Agaciro = 5 \, imodoka$$

#### Igiteranyo cyuzuye

$$Agaciro = Agaciro \cdot (100 / Ijanisha) \\[1ex]$$
Urugero: Igiciro Cyuzuye Niki niba imodoka 5 ari 50%
$$Agaciro = 5 \cdot (100 / 50) \\ Agaciro = 10\; imodoka$$
