1.4 + (2/5)e = (3/15)e - 0.8
1.4 + (2/5)e = (1/5)e - 0.8
(2/5)e - (1/5)e = - 0.8 - 1.4
(1/5)e = - 2.2
e = -2.2 * 5
e = -11
1.4 + (2/5)e = (1/5)e - 0.8
(2/5)e - (1/5)e = - 0.8 - 1.4
(1/5)e = - 2.2
e = -2.2 * 5
e = -11

Should be shown as :-
1•4 + (2/5) e = (3/15) e - 0•8
(3/15) e = - 2•2
e = - 11
1•4 + (2/5) e = (3/15) e - 0•8
(3/15) e = - 2•2
e = - 11
