Answer 1

Answer:

1.)10/47

2.)5/16

3.)13/3

Step-by-step explanation:

1.)    1/6÷ {5/6-(1/20)}

1/6÷ {(50-3)/20}

1/6÷ 47/60

1/6*60/47

=10/47

2.)  5/4*{3/4-(2/3-1/6)}

    5/4*{3/4-(3/6)}

   5/4*{(3-2)/4}

   5/4*1/4=5/16

3.)   6-[5/2-{1/4+(6+2-1)/12}]

      6-[5/2-{1/4+7/12}]

      6-[5/2-(3+7)/12]

       6-[5/2-10/12]

       6-5/3=13/3
