Answer 1

$\tt{} \frac{1}{7} + \frac{2}{5} - \frac{3}{4}$

$\tt{} \frac{1 \times 20}{7 \times 20} + \frac{2 \times 28}{5 \times 28} - \frac{3 \times 35}{4 \times 35}$

$\tt{} \frac{20}{140} + \frac{56}{ 140} - \frac{105}{140}$

$\tt{} \frac{20 + 56 - 105}{140}$

$\tt{} \frac{ - 29}{140}$

$\tt{} - \frac{29}{140}$
