Question

0,52=? 0,(93)=? 1,2(5) X pe 25 = 8 pe 20 2x:4=>x€{...}

Answer 1

$0.52 = \frac{52}{100} = \frac{26}{50} = \frac{13}{25 }$

$0.93 = \frac{93}{99} = \frac{31}{33}$

$1.2(5) = \frac{125 - 12}{90} = \frac{113}{90}$

$\frac{x}{25} = \frac{8}{20} \\ 20 \times x = 25 \times 8 \\ 20 \times x = 200 \\ x = \frac{200}{20 } \\ x = 10$
