please dengan caranya yah

[tex] \frac{128}{100} \div \frac{1}{25} = \frac{128}{100} \times \frac{25}{1} = \frac{3200}{100} = 32 \\ \frac{32}{1} + \frac{25}{4} = \frac{128}{4} + \frac{25}{4} = \frac{153}{4} \\ \frac{153}{4} - \frac{1329}{1000} = \frac{3250}{1000 } - \frac{1329}{1000} = \frac{1921}{1000} = 192.1[/tex]
maaf kalau salah

12,8 : 1/25 + 6 1/4 - 132,9 =
[tex]( \frac{128}{10} \div \frac{1}{25} )+ \frac{25}{4} - \frac{1329}{10} \\ = ( \frac{128}{10} \times \frac{25}{1} ) + \frac{25}{4} - \frac{1329}{10} \\ = \frac {3200}{10} + \frac{25}{4} - \frac{1329}{10} \\ = (\frac{3200}{10} - \frac{1329}{10} ) + \frac{25}{4} \\ = \frac{1871}{10} + \frac{25}{4} = \frac{7484}{40} + \frac{250}{40} \\ = \frac{7234}{40} = 180.85[/tex]
