a)
1, 3 = 13 / 10
b)
2, 1 ( 8 ) = ( 218 - 21 ) / 90 = 197 / 90
c)
0, 36 = 36 / 100 = 9 / 25
d)
45, 8 = 458 / 10 = 229 / 5
e)
0, 34 ( 6 ) = ( 346 - 34 ) / 900 = 312 / 900 = 104 / 300
Răspuns:
a) [tex]\frac{13}{10}[/tex] c) [tex]\frac{9}{25}[/tex] e) [tex]\frac{26}{75}[/tex]
b) [tex]\frac{197}{90}[/tex] d) [tex]\frac{229}{5}[/tex]
Explicație pas cu pas:
a) 1,3 = [tex]\frac{13}{10}[/tex]
b) 2,1(8) = [tex]2\frac{18-1}{90}[/tex] = [tex]2\frac{17}{90}[/tex] = [tex]\frac{197}{90}[/tex]
c) 0,36 = [tex]\frac{36}{100}[/tex] = [tex]\frac{9}{25}[/tex]
d) 45,8 = [tex]\frac{458}{10}[/tex] = [tex]\frac{229}{5}[/tex]
e) 0,34(6) = [tex]\frac{346-34}{900}[/tex] = [tex]\frac{312}{900}[/tex] = [tex]\frac{26}{75}[/tex]
