1. \(\displaystyle 80\) -ді \(\displaystyle 35{\small}\)-ке бөлейік
\(\displaystyle 80{\small }\)-нен максималды қанша \(\displaystyle \color{blue}{35}\)-ті алуға болатынын табайық.
Яғни, \(\displaystyle 80\)-ді \(\displaystyle \color{blue}{35}{\small }\)-ке бөлгендегі толымсыз бөліндіні табамыз.
\(\displaystyle 80=\color{green}{2} \cdot \color{blue}{35} +10{\small}\) болса,
онда \(\displaystyle 35 \)-ті \(\displaystyle \color{green}{2}\) рет алуға болады.
Сондықтан \(\displaystyle \color{green}{2}\)-ні келесі санмен бөліндіге жазамыз:
\(\displaystyle -\) | \(\displaystyle \small 4\) | \(\displaystyle \small 3\) | \(\displaystyle \small 0\) | \(\displaystyle \small 5\) | \(\displaystyle \small 35\) | | |
\(\displaystyle \small 3\) | \(\displaystyle \small 5\) | | | \(\displaystyle \small 1\) | \(\displaystyle \small \color{green}{ 2}\) | \(\displaystyle \small ?\) |
| \(\displaystyle -\) | \(\displaystyle \small 8\) | \(\displaystyle \small 0\) | | | | |
\(\displaystyle \small ?\) | \(\displaystyle \small ?\) | | | | |
| \(\displaystyle -\) | \(\displaystyle \small ?\) | \(\displaystyle \small ?\) | \(\displaystyle \small ?\) | | | |
| \(\displaystyle \small ?\) | \(\displaystyle \small ?\) | \(\displaystyle \small ?\) | | | |
| | | | \(\displaystyle \small 0\) | | | |
2. Әрі қарай, бағанда \(\displaystyle 80\)-нен көбейтінді \(\displaystyle \color{blue}{35}\cdot \color{green}{2}=\color{green}{70}{\small }\) азайтамыз:
\(\displaystyle -\) | \(\displaystyle \small 4\) | \(\displaystyle \small 3\) | \(\displaystyle \small 0\) | \(\displaystyle \small 5\) | \(\displaystyle \small 35\) | | |
\(\displaystyle \small 3\) | \(\displaystyle \small 5\) | | | \(\displaystyle \small 1\) | \(\displaystyle \small \color{green}{ 2}\) | \(\displaystyle \small ?\) |
| \(\displaystyle -\) | \(\displaystyle \small \color{cyan}{8}\) | \(\displaystyle \small \color{cyan}{0}\) | | | | |
\(\displaystyle \small \color{green}{ 7}\) | \(\displaystyle \small \color{green}{ 0}\) | | | | |
| \(\displaystyle -\) | \(\displaystyle \small 1\) | \(\displaystyle \small 0\) | \(\displaystyle \small ?\) | | | |
| \(\displaystyle \small ?\) | \(\displaystyle \small ?\) | \(\displaystyle \small ?\) | | | |
| | | | \(\displaystyle \small 0\) | | | |
3. \(\displaystyle 430{\underline 5}{\small }\) бірліктер разрядынан санды аламыз
\(\displaystyle -\) | \(\displaystyle \small 4\) | \(\displaystyle \small 3\) | \(\displaystyle \small 0\) | \(\displaystyle \small 5\) | \(\displaystyle \small 35\) | | |
\(\displaystyle \small 3\) | \(\displaystyle \small 5\) | | | \(\displaystyle \small 1\) | \(\displaystyle \small 2\) | \(\displaystyle \small ?\) |
| \(\displaystyle -\) | \(\displaystyle \small 8\) | \(\displaystyle \small 0\) | | | | |
\(\displaystyle \small 7\) | \(\displaystyle \small 0\) | | | | |
| \(\displaystyle -\) | \(\displaystyle \small 1\) | \(\displaystyle \small 0\) | \(\displaystyle \small \bf 5\) | | | |
| \(\displaystyle \small ?\) | \(\displaystyle \small ?\) | \(\displaystyle \small ?\) | | | |
| | | | \(\displaystyle \small 0\) | | | |
\(\displaystyle 105{\small .}\) санын алдық
