Умножение числа 2 и на 2
\[\begin{aligned} 8 \cdot 4 &= 32 & \qquad 9 \cdot 3 &= 27 & \qquad 7 \cdot 5 &= 35 \\ 32 : \textcolor{#e03131}{\mathbf{8}} &= 4 & \qquad 27 : \textcolor{#e03131}{\mathbf{3}} &= 9 & \qquad 35 : 5 &= \textcolor{#e03131}{\mathbf{7}} \\ \textcolor{#e03131}{\mathbf{32}} : 4 &= 8 & \qquad \textcolor{#e03131}{\mathbf{27}} : \textcolor{#e03131}{\mathbf{9}} &= 3 & \qquad \textcolor{#e03131}{\mathbf{35}} : \textcolor{#e03131}{\mathbf{7}} &= 5 \end{aligned}\]
\[\begin{array}{ccl} \textcircled{1} & \textcolor{#e03131}{\rule[0.32em]{2.2em}{0.09em}} & \boxed{8 \cdot 2 = 16} \\[4pt] \textcircled{2} & \textcolor{#e03131}{\rule[0.32em]{2.2em}{0.09em}} & \boxed{8 : 2 = 4} \\[4pt] \textcircled{3} & \textcolor{#e03131}{\rule[0.32em]{2.2em}{0.09em}} & \boxed{8 - 2 = 6} \end{array}\]
\(35 - 17 = \textcolor{#e03131}{\mathbf{18}}\text{ (л.)}\)
Ответ: \(\textcolor{#e03131}{\mathbf{18}}\) лампочек.
