Answer:
1. percentage id a number or ratio expressed as fraction of 100. it is often denoted using '%' although the abbreviations "pct", and sometimes"pc" are also used. A percentage is a dimensionless number; it has no unit of measurement.
2.
[tex]62\% = \frac{31}{50} [/tex]
solution on example 1: 62%
[tex]62\% = \frac{62}{100} or \: 62 \div 100 = 0.62 \\ = \frac{0.62}{1} \times \frac{100}{1008} \\ = \frac{62}{100} \div \frac{2}{2} \\ = \frac{31}{50} [/tex]
[tex]10\% = \frac{1}{10} [/tex]
Solution on example 2: 10%
[tex]10\% = \frac{10}{100} \: or \: 10 \div 100 = 0.1 \\ = \frac{0.1}{1} \times \frac{10}{10} \\ = \frac{1}{10} [/tex]
3.
[tex]3. \: example \: 1. \: \\ 25\% = 0.25 \\ solution \\ 25 \div 100 = 0.25[/tex]
[tex]example \: 2. \\ 4.5\% = 0.045 \\ solution \\ 4.5 \div 100 = 0.045[/tex]
