Question

0,25+(0,9 ̂-0,1 ̂ )-1,02 ̂

Answer 1

Respuesta:

$\boxed{ \bold{\frac{7}{60}}}$

RESOLUCIÓN:

$\bold{0,25 + (0, \overline{9} - 0, \overline{1})-1, 0 \overline{2}}$

$\bold{\frac{25}{100} + \left ( \frac{9}{9}- \frac{1}{9} \right )- \frac{102-10}{90}}$

$\bold{\frac{1}{4} + \left ( \frac{8}{9} \right )- \frac{92}{90}}$

$\bold{\frac{1\cdot 45}{4 \cdot 45} + \frac{8 \cdot 20}{9 \cdot 20}- \frac{92 \cdot 2}{90 \cdot 2}}$

$\bold{\frac{45}{180} + \frac{160}{180}- \frac{184}{180}}$

$\bold{\frac{45+160-184}{180}}$

$\bold{\frac{21}{180}}$

$\bold{\frac{7}{60}}$
