  1. 3/4 \sqrt{16} + 2 : |-1/2| – 7 (-1/7)
    =  3/4 . 4 + 2 : 1/2 + 1
    = 3 + 2 . 2 + 1
    = 3 + 4+1
    =  7+1
    = 8

  2. $@Shin$
    $\dfrac{3}{4}$ . $\sqrt{16}$ +2 : $|\dfrac{-1}{2}|$ -7 . $(\dfrac{-1}{7})$
    = $\dfrac{3}{4}$ .8 +2 : $\dfrac{1}{2}-7$ . $(\dfrac{-1}{7})$
    =6+1+1
    =8
