Answer 1

Ответ:

2,24

Объяснение:

$\displaystyle (\frac{9}{22}+1\frac{12}{33} ) \times 1,32-\frac{8}{13} \times 0,1625= 2,24\\ \\ \\ 1) \ \frac{9}{22}+1\frac{12}{33} =\frac{9}{22} +\frac{45}{33} =\frac{9 \times 3}{22 \times 3}+ \frac{45 \times 2}{33 \times 2} =\frac{27}{66} +\frac{90}{66}=\frac{117}{66} \\ \\ \\ 2) \ \frac{117}{66} \times 1,32 = \frac{117}{66} \times \frac{132}{100} = \frac{117}{1} \times \frac{2}{100}=\frac{117 \times 1}{50} =\frac{117}{50}$

$\displaystyle 3) \ \frac{8}{13} \times 0,1625 = \frac{8}{13} \times \frac{13}{80} =\frac{1 \times 1}{1 \times 10} =\frac{1}{10} \\ \\ \\ 4) \ \frac{117}{50}-\frac{1}{10}=\frac{117}{50} - \frac{5}{50} =\frac{112}{50} =\frac{56}{25}= 2,24$
