Answer 1

1.

$\frac{3}{5} + \frac{11}{4} + 2 \frac{3}{10} = \frac{3}{5} + \frac{11}{4} + \frac{23}{10} = \\ \frac{67}{20} + \frac{23}{10} = \frac{900}{20} = 45$

2.

$6 \frac{3}{4} - \frac{11}{4} - 1 \frac{2}{5} = \frac{27}{4} - \frac{11}{4} - \frac{7}{5} = \\ \frac{16}{4} - \frac{7}{5} = \frac{52}{20} = \frac{26}{10} = \frac{13}{5}$
