Answer 2

(d) is not true

$43/56\neq -43/56$

Step-by-step explanation:

$(a) 8/7+3/8=3/8+8/7$

$85/56=85/56$

$(b) 8/7\times 3/8=3/8\times 8/7$

           $3/7=3/7$

$(c) 8/7/3/8=8/7\times 8/3$

$8/7\times 8/3=64/21$

$64/21=64/21$

$(d)8/7-3/8=3/8-8/7$

$43/56\neq -43/56$

Option (d) is not true
