$$26.\quad \frac{1}{3} : \frac{2}{3} + 0,228 : [(1,5291 - \frac{14,53662}{3 - 0,095 \cdot 0,305}) : 0,12].$$
Ҳал:
\(26. \frac{1}{3} : \frac{2}{3} + 0,228 : [(1,5291 - \frac{14,53662}{3 - 0,095 \cdot 0,305}) : 0,12] = 10.\)

\(
1) \frac{1}{3} : \frac{2}{3} = \frac{1}{3} \cdot \frac{3}{2} = \frac{1 \cdot 3}{3 \cdot 2} = \frac{1 \cdot 1}{1 \cdot 2} = \frac{1}{2} = 0,5;
\)

\(
2) 3 - 0,095 = 2,905;
\)

\(
3) \frac{14,53662}{2,905} = 14,53662 : 2,905 = 5,004;
\)

\(
4) 5,004 \cdot 0,305 = 1,52622;
\)

\(
5) 1,5291 - 1,52622 = 0,00288;
\)

\(
6) 0,00288 : 0,12 = 0,024;
\)

\(
7) 0,228 : 0,024 = 9,5;
\)

\(
8) 0,5 + 9,5 = 10.
\)
