Question

Calculati: 145:40 ; 155,6:3,2 ; 25,3:0,1 ; 105:3,6 sa fie una sub alta calculat, nu rezultatul direct, va rog mult cat mai repede.

Answer 1

$\frac{145}{40} = \frac{29}{8} =3intregi \frac{5}{8}$
$\frac{155,6}{3,2} = \frac{1556}{10} : \frac{32}{10} = \frac{1556}{10} * \frac{10}{32} = \frac{1556}{32} = \frac{389}{8} =48,625$
$\frac{25,3}{0,1} = \frac{253}{10} : \frac{1}{10} = \frac{253}{10} *10=253$
$\frac{105}{3,6} =105: \frac{36}{10} =105* \frac{10}{36} = \frac{1050}{36} = \frac{525}{18} =29intregi \frac{3}{18}$
