Ответ:

4 5/12 * 8 23/46 =

$4\frac{5}{12}*8\frac{23}{46} =\frac{4*12+5}{12} *\frac{46*8+23}{46} =\frac{53}{12}* \frac{391}{46}= \frac{53}{12}*\frac{17}{2}=\frac{901}{24}=37\frac{13}{24}$ ≈ 37,54

Answer 2

Пошаговое объяснение:

$4 \frac{5}{12} \times 8 \frac{23}{46} = 4 \frac{5}{12} \times 8 \frac{1 \times 23}{2 \times 23} = 4 \frac{5}{12} \times 8 \frac{1}{2} = \frac{5 + 4 \times 12}{12} \times \frac{1 + 8 \times 2}{2} = \frac{53}{12} \times \frac{17}{2} = \frac{53 \times 17}{12 \times 2} = \frac{901}{24} = \frac{37 \times 24 + 13}{24} = 37 \frac{13}{24}$
