c)25/100=
d)1,6/100=
e)3,2/10=
f)15/15=
g)8/400
h)1,6/10=
i)4/5=

Answer 1

Explicação passo-a-passo:

a)

$= \frac{23}{100} = 23\%$

b)

$= \frac{135}{100} = 135\%$

c)

$= \frac{25}{100} = 25\%$

d)

$= \frac{1.6}{100} = 1.6\%$

e)

$= \frac{3.2}{10} = \frac{3.2 \times 10}{10 \times 10} = \frac{32}{100} = 32\%$

f)

$= \frac{15}{15} = 100\%$

g)

$= \frac{8}{400} = \frac{ \frac{8}{4} }{ \frac{400}{4} } = \frac{2}{100} = 2\%$

h)

$= \frac{1.6}{10} = \frac{1.6 \times 10}{10 \times 10} = \frac{16}{100} = 16\%$

i)

$= \frac{4}{5} = \frac{4 \times 20}{5 \times 20} = \frac{80}{100} = 80\%$
