Помогите пожалуйста.

=(3 1/4+7/6*9/14)*7/16+46/9*3/23=(3 1/4+1/2*3/2)*7/16+2/3=
(3 1/4+3/4)*7/16+2/3=4/1*7/16+2/3=7/4+2/3=21/12+8/12=29/12=
2 5/12

1) 7/6 : 14/9 = 7/6 * 9/14 = 3/4
2) 3 1/4 + 3/4 = 3 4/4 = 4
3) 4/1 : 16/7 = 4/1 * 7/16 = 7/4= 1 3/4
4) 46/9 : 23/3 = 46/9 * 3/23 = 2/3
5) 1 3/4 + 2/3 = 1 17/12 = 2 5/12
