Jawaban :

$= 100\% \times \frac{2}{5} \\ = \frac{100}{100} \times \frac{2}{5} \\ = \frac{100 \times 2}{100 \times 5} \\ = \frac{200}{500} \\ = \frac{2}{5}$

$= 20\% + \frac{3}{4} \\ = \frac{20}{100} + \frac{3}{4} \\ = \frac{80 + 300}{400} \\ = \frac{380}{400} \\ = \frac{38}{40}$

= 9⁹⁰ ÷ 9¹⁰⁰

= 9⁹⁰- ¹⁰⁰

= 9-¹⁰
