Answer 1

Explicación paso a paso:

La fracción generatriz de un número decimal es la fracción irreductible que da como resultado dicho número decimal.

38) Escribir como expresión decimal o como fracción según corresponda.

$\frac{7}{4} = 1,75\\\\3,21 = \frac{321}{100} \\\\3,001=\frac{3001 - (3)}{999} = \frac{2998}{99} \\\\11,5=\frac{115 - (11)}{9} = \frac{104}{9} \\\\1,054=\frac{1054 - (10)}{990}=\frac{1044}{990}=\frac{58}{55}\\\\\frac{6}{7} = 0,857142857142857\\\\0,09=\frac{9 - (0)}{90}=\frac{9}{90}=\frac{1}{10}\\\\12,45 = \frac{1245}{100} = \frac{249}{20}\\\\1,42=\frac{142 - (1)}{99} = \frac{141}{99} = \frac{47}{33}\\\\3,09=\frac{309 - (30)}{90}=\frac{279}{90}=\frac{31}{10}\\\\\frac{4}{3} = 1,3333..$

$5,7=\frac{57 - (5)}{9} = \frac{52}{9} \\\\0,28=\frac{28 - (0)}{99} = \frac{28}{99} \\\\4,002 = \frac{4002}{1000} = \frac{2001}{500}\\\\0,185=\frac{185 - (18)}{900}=\frac{167}{900}=\frac{167}{900}\\\\\frac{31}{5} = 6,2$

$8,23=\frac{823 - (82)}{90}=\frac{741}{90}=\frac{247}{30}\\\\1,432=\frac{1432 - (14)}{990}=\frac{1418}{990}=\frac{709}{495}\\\\2,8 = \frac{28}{10} = \frac{14}{5}\\\\2,03=\frac{203 - (2)}{99} = \frac{201}{9} = \frac{67}{3}$

$\frac{21}{5} = 4,2\\\\6,043=\frac{6043 - (604)}{900}=\frac{5439}{900}=\frac{1813}{300}\\\\7,203=\frac{7203 - (72)}{990}=\frac{7131}{990}=\frac{2377}{330}\\\\10,1=\frac{101 - (10)}{9} = \frac{91}{9} \\\\4,9=\frac{49 - (4)}{9} = \frac{45}{9} =5$
