Answer 1

(a) \(0.65\)

\(0.65= 0.65\times 100\%\)

= \(\frac{65\times100}{100}\%\)

= \(65\%\)

(b) \(2.1\)

\(2.1=2.1\times100\%\)

= \(\frac{21\times100}{10}\%\)

= \(210\%\)

---

(c) \(0.02\)

\(0.02=0.02\times100\%\)

= \(\frac{2\times100}{100}\%\)

= \(2\%\)

---

(d) \(12.35\)

\(12.35=12.35\times100\%\)
