transforma in fractii ordinare nr:0,37;0, (83);4,(7);0,2(23). Va rog repede! dau coroana!

[tex]0.37 = \frac{37}{100} [/tex]

[tex]0.(83) = \frac{83}{99} [/tex]

[tex]4.(7) = \frac{47 - 4}{9} = \frac{43}{9} [/tex]

[tex]sau[/tex]

[tex]4.(7) = 4 \frac{7}{9} = \frac{4 \times 9 + 7}{9} = \frac{36 + 7}{9} = \frac{43}{9} [/tex]

[tex]0.2(23) = \frac{223 - 2}{990} = \frac{221}{990} [/tex]

0,37 = 37 / 100

0,(83) = 83 / 99

4,(7) = 4    7 / 9 = 43 / 9 

0,2(23 ) = (  223 - 2 )  / 990 = 221 / 990
