(minus 1 and 2 / 1) / (+ 3 / 4) * (minus 0.2) * 1 and 4 / 1.4 * (minus 3 / 5) =?

(minus 1.2) / (+ 3 / 4) * (minus 0.2) * 1.4 / 1.4 * (minus 3 / 5)
=-3/2*4/3*0.2*7/4*5/7*3/5
=-(3/2*4/3)*(0.2*3/5)*(7/4*5/7)
=-2*3/25*5/4
=-3/10

-1 divided by [minus 3 and 2 / 5]

--1 divided by [minus three and two fifths]
=--1 divided by [17 out of 5]
=(-- 1) times (- - 5 / 17)
=5/17.

-1.5 + 2.84 + (minus 3.84) + (minus 3 / 2)

-1.5 + 2.84 + (minus 3.84) + (minus 3 / 2)
=(- 1.5 + 3 / 2) + [2.84-3.84]
=-3-1
=-4
