Question

transformati in fractii ordinare ireductibile:a)1,25 b)3,4 c)0,(6) d)1,(3) e)1,2(3).

Answer 1

a) 1,25 = $\frac{125}{100}$ = $\frac{5}{4}$
b) 3,4 = $\frac{34}{10}$ = $\frac{17}{5}$
c) 0,(6) = $\frac{6}{9} = \frac{2}{3}$
d) $1,(3) = \frac{13-1}{9} = \frac{4}{3}$
e) 1,2(3) = $\frac{123-12}{90}= \frac{111}{90}= \frac{37}{30}$
