1) Произведение чисел 18 и 5 разделить на 15.
\(18 \cdot 5 : 15 = \textcolor{#e03131}{\mathbf{6}}\)
2) Произведение чисел 26 и 3 разделить на 13.
\(26 \cdot 3 : 13 = \textcolor{#e03131}{\mathbf{6}}\)
3) Частное чисел 48 и 16 умножить на 24.
\(48 : 16 \cdot 24 = \textcolor{#e03131}{\mathbf{72}}\)
4) Произведение чисел 32 и 3 разделить на частное чисел 88 и 11.
\(32 \cdot 3 : (88 : 11) = \textcolor{#e03131}{\mathbf{12}}\)
