Вопрос:

Вычислите: (9/22+1 12/33)*1,32-8/13*0,1625.

Ответ:

\[\left( \frac{9}{22} + 1\frac{12}{33} \right) \cdot 1,32 - \frac{8}{13} \cdot 0,1625 =\]

\[= \left( \frac{9^{\backslash 3}}{22} + \frac{45^{\backslash 2}}{33} \right) \cdot \frac{132}{100} - \frac{8}{13} \cdot \frac{1625}{10000} =\]

\[= \left( \frac{27}{66} + \frac{90}{66} \right) \cdot \frac{33}{25} - \frac{8 \cdot 13}{13 \cdot 80} =\]

\[= \frac{117}{66} \cdot \frac{33}{25} - \frac{1}{10} = \frac{117 \cdot 33}{66 \cdot 25} - \frac{1}{10} =\]

\[= \frac{117}{50} - \frac{1^{\backslash 5}}{10} = \frac{117}{50} - \frac{5}{50} =\]

\[= \frac{112}{50} = \frac{224}{100} = 2,24\]
