Answer 1

a) 29/4 - 5/2 - 23/6 + 7/3 = 87/12 - 30/12 - 46/12 + 28/12 = 39/12 = 3 1/4
b)21/5 - 13/4 + 9 /8 - 27/10 = 168/40 - 130/40 +45/40 - 108/40 = -25/40 = -1/8
c) 43/12 - 8/5 - 31/20 +11/6= 215/60 - 96/60 - 93/60 +110/60 = 136/60= 2 16/60 = 2 8/30 = 2 4/15
d)293/36 - 31/8 - 17/8 - 25/18 = 586/72 - 279/72 - 153/72 - 100/18 = 54/18 = 3e) 16/5 -{5/2-[11/4-(21/10-5/4)]}=128/40-{100/40-[110/40-(84/40-50/40)]}= 128/40-{100/40-[110/40-34/40]}=128/40-{100/40-76/40}=128/40-24/40=104/40=2 24/40= 2 12/20= 2 6/10= 2 3/5f) 13/2-[16/3-(17/4-16/5)]=390/60-[320/60-(255/60-192/60)]=390/60-[320/60-63/60]=390/60-257/60=133/60-2 13/60
g) 41/5-[25/4-(13/3-5/2)]= 492/60-[375/60-(260/60-150/60)]= 492/60-[375/60-110/60]= 492/60-265/60=227/60=3 47/60h) 28/3-{29/4-[26/5-(19/6-3/2)]}= 560/60-{435/60-[312/60-(190/60-90/60)]}= 560/60-{435/60-[312/60-100/60]}=560/60-{435/60-212/60}=560/60-223/60=337/60= 5 37/60
