Question

Determine as frações irredutíveis das porcentagens.

a) 25% b)60%

c)150% d) 0,5%​

Answer 1

a)

$25\% = \frac{25 \div 25}{100 \div 25} = \frac{1}{4}$

b)

$60\% = \frac{60 \div 20}{100 \div 20} = \frac{3}{5}$

c)

$150\% = \frac{150 \div 50}{100 \div 50} = \frac{3}{2}$

d)

$0,5\% = \frac{0,5}{100} = \frac{5 \div5 }{1000 \div 5} = \frac{1}{200}$
