Question

represente os numeros racionais na forma fracionária e na forma percentual:
​

Answer 1

b) 1/5 x 20/20 = 20/100 = 20%

c) 2/4 x 25/25 = 50/100 = 50%

d) 6/8 x 12,5/12,5 = 75/100 = 75%

Answer 2

Olá,

b)

$\frac{1}{5} = \frac{1 \times 20}{5 \times 20} = \frac{20}{100} = 20\%$

c)

$\frac{2}{4} = \frac{2 \times 25}{4 \times 25} = \frac{50}{100} = 50\%$

d)

$\frac{6}{8} = \frac{6 \div 2}{8 \div 2} = \frac{3}{4} = \frac{3 \times 25}{4 \times 25} = \frac{75}{100} = 75\%$
