E- 2/3
F- 2/3
G- 4/5
H- 1/5
I- 1/5
J- 1/25
K- 7/20
K- 2/5

Answer 2

a-4/12 = m.d.c = 4 = 1/3
b-3/6=m.d.c = 3 = 1/2
c-5/20=m.d.c=5=1/4
d-9/7=m.d.c=9=1/3
e-10/15=m.d.c=5=2/3
f-6/9=m.d.c=3=2/3
g-12/15 - m.d.c=3=4/5
h-20/100=m.d.c=20=1/5
i-8/40=m.d.c=8=1/5
j-4/100=m.d.c=4=1/25
k-21/60=m.d.c=3=7/20
l-14/35=m.d.c=7=2/5
