Answer 1

    1 2/3+4*(3 3/4 - 5/6) : 6 4/11=3 1/2

1)   3 3/4 - 5/6=3 9/12 - 10/12=2 21/12 - 10/12=2 11/12

2)   4 * 2 11/12=4*2+4*11/12=8+11/3=8+3 2/3=11 2/3

3)   11 2/3 : 6 4/11=35/3 : 70/11=35/3 * 11/70=11/6=1 5/6

4)    1 2/3+1 5/6=1 4/6+1 5/6=2 9/6=3 3/6=3 1/2

Answer 2

1 2/3+4*(3 3/4-5/6) :6 4/11=$3\frac{1}{2}$

1)3 3/4-5/6=$2\frac{11}{12}$

2)$4* 2\frac{11}{12}=$$11\frac{2}{3}$

3)$11\frac{2}{3} / 6\frac{4}{11} = 1 \frac{5}{6}$

4)$1\frac{2}{3} +1 \frac{5}{6} =3\frac{1}{2}$
