Answer 1

A)3+1 1/5·3/4=3+6/5·3/4=3+9/20=3 9/20
b)(2 5/6-1 1/3)·2 1/4-1/6=(2 5/6-1 2/6)·2 1/4-1/6=1 3/6·2 1/4-1/6=9/6· 9/4-1/6= 27/8-1/6=3 3/8-1/6=3 9/24-4/24=3 5/24
c)2-1 1/2·2/5=2-3/2·2/5=2-3/5=1 5/5-3/5=1 2/5
d) (2 1/2+4 1/6):1 1/3-1/8=(2 3/6+4 1/6):1 1/3-1/8= 6 4/6:1 1/3-1/8=40/6:4/3-1/8 =40/6·3/4=10/2-1/8=5 -1/8=4 8/8-1/8=4 7/8
