Question

scrieti sub forma de fractii ordinare: 0,27(73)
3,0(3)
12,10(3)
7,8(3)

Answer 1

0,27(73) = $\frac{2773 - 27}{9900} = \frac{2746}{9900}$
3,0(3) = $3 + \frac{03 - 0}{90} = 3 + \frac{3}{90}$
12,10(3) = $12 + \frac{103 - 10}{900} = 12 + \frac{93}{900}$
7,8(3) = $7 + \frac{83 - 8}{90} = 7 + \frac{75}{90}$
