Question

alguém me ajuda com a fração por favor​

Answer 1

Resposta:

$0.124 = \frac{124}{999} \\ 1.27 = \frac{14}{11} \\ 1.351 = \frac{50}{37} \\ 2.538 = \frac{2536}{999} \\ 0.1345 = \frac{1345}{9999} \\ 1.64 = \frac{163}{99}$

Answer 2

Resposta:

Explicação passo-a-passo:

a.0,124124...

x=0,124124...

1000x=124,124124...

1000x-x=124,124124...-0,124124...

999x=124

x=124/999

b.1,2727...

x=1,2727...

100x=127,2727...

100x-x=127,2727...-1,2727...

99x=126

x=126/99

c.1,351351351...

x=1,351351...

1000x=1351,351351...

1000x-x=1351,351351...-1,351351...

999x=1350

x=1350/999

d.2,538538...

x=2,538538...

1000x=2538,358358...

1000x-x=2538,358358...-2,538538...

999x=2536

x=2536/999

e. 0,13451345...

x=0,13451345...

10000x=1345,13451345...

10000x-x=1345,13451345...-0,13451345...

9999x=1345

x=1345/9999

f.1,6464...

x=1,6464...

100x=164,6464...

100x-x=164,6464...-1,6464...

99x=163

x=163/99
