 2\frac{3}{5}  + (\frac{48}{100} - 2\frac{1}{4}) -30
 %
 \frac{13}{5} + (\frac{48}{100} - \frac{9}{4}) -\frac{30}{100}
 \frac{13}{5} + (\frac{48}{100} - \frac{225}{100}) - \frac{30}{100}
 \frac{13}{5} + (\frac{-177}{100}) - \frac{30}{100}  [tex] \frac{260}{100} + (\frac{-177}{100}) - \frac{30}{100} =  \frac{53}{100}
