Question

Scrieti sub forma zecimala numerele : 1/8 , 14/9 , -3 intregi si 5/6 , 2intregi si 5/7 , 7/18 , -7/9 , 34/900 , 21/990 ; E urgent ! Primului care imi zice raspuns corect ii dau coroana .

Answer 1

$\displaystyle \frac{1}{8} =0,125 \\ \\ \frac{14}{9} =1,(5) \\ \\ -3 \frac{5}{6} =- \frac{23}{6} =-3,8(3) \\ \\ 2 \frac{5}{7} = \frac{19}{7} =2,(714285 ) \\ \\ \frac{7}{18} =0,3(8) \\ \\ - \frac{7}{9} =-0,(7)$

$\displaystyle \frac{34}{900} =0,03(7) \\ \\ \frac{21}{990} =0,0(21)$

Answer 2

1 / 8 = 0 , 125
14 / 9 = 1, ( 5 )
-3 intregi si 5 / 6 = - 23 / 6 =-3 , 8 ( 3 )
2 intregi si 5 / 7 = 19 / 7 = 2 , 7142857
7 / 18 = 0 , 3 ( 8 )
34 / 900 = 0 , 03 ( 7 )
21 / 990 = 0 , 02 ( 12)
