Answer 1

a) 1/4+5/4=6/4
=3/2
b) 23/17+11/17=34/17
=2
c) 16/93+15/93=31/93
=1/3
d) 11/14+23/14=34/14
=17/7
e) 3/16+15/16=18/16
=9/8
f) 1 (intreg) 1/8+ 1 (intreg) 3/8= 1×8+1/8+1×8+3/8
=9/8+11/8
=20/8
=5/2
g) 1 (intreg)3/10+3 (intregi)1/10=1×10+3/10+3×10+1/10
=13/10+31/10
=44/10
=22/5
h)2 (intregi)3/5+3 (intregi)2/5=2×5+3/5+3×5+2/5
=13/5+17/5
=30/5
=6
