Answer 1

1)

$( \frac{43}{7} - \frac{23}{4} ) \times \frac{14}{11} + ( \frac{15}{4} - \frac{11}{6} ) \times 6 = ( \frac{172}{28} - \frac{161}{28} ) \times \frac{14}{11} + ( \frac{45}{12} - \frac{22}{12} ) \times 6 = \frac{11}{28} \times \frac{14}{11} + \frac{23}{12} \times 6 = \frac{1}{2} + \frac{23}{2 } = \frac{24}{2} = 12$

2)

$\frac{99}{19} \times \frac{25}{7} + \frac{34}{19} \times \frac{25}{7} - \frac{5}{3} = \frac{2475}{133} + \frac{850}{133} - \frac{5}{3} = \frac{3325}{133} - \frac{5}{3} = \frac{9975}{399} - \frac{665}{399} = \frac{9310}{399} = 23 \times \frac{1}{3}$
