Answer:
[tex]Solution,\\First=(\frac{-2}{3} +\frac{3}{5} )*\frac{1}{2} \\=-\frac{1}{15} *\frac{1}{2} =-\frac{1}{30} \\Second=(-1/30+3/5)*1/2\\=17/30*1/2=17/60\\Third=(17/60+3/5)*1/2\\=53/60*1/2=53/120\\Fourth=(53/120+3/5)*1/2\\=25/24*1/2=25/48[/tex]
First number=-1/30
Second number=17/60
Third number=53/120
Fourth number=25/48
