Answer 1

a)4/5+ 1/10 = 8/10 + 1/10 = 9/10

b)1/6 + 2/3 = 1/6 + 4/6 = 5/6

c)8/9 - 1/3 = 8/9 - 3/9 = 5/9

d)13/10 - 1/5 = 13/10 - 2/10 = 11/10 = 1 1/10

e) 2/3 + 1/5 = 10/15 + 3/15 = 13/15

f)4/7 - 1/2 = 8/14 - 7/14 = 1/14

g)2 2/5 + 3 1/2 = 2 4/10 + 3 5/10= 5 9/10

h)4 3/7 + 2 2/3 = 4 9/21 + 2 14/21 = 6 23/21 = 72/21

i)4/5 - 2/3 = 12/15 - 10/15 = 2/15

j) 5/7 - 1/4 = 20/28 - 7/28 = 13/28

k)2 3/8 - 1 1/6 = 2 9/24 - 1 4/24 = 1 5/24

l)4 1/2 - 2 3/5 = 4 5/10 - 2 6/10 = 3 15/10 - 2 6/10 = 1 9/10

m)4 1/4 - 2 2/3 = 4 3/12 - 2 8/12 = 3 15/12 - 2 8/12 = 1 5/12

n)5 1/9 - 1 5/6 = 5 2/18 - 1 15/18 = 4 20/18 - 1 15/18 = 3 5/18

o) 2 1/15 - 1/10= 2 2/30 - 3/30 = 1 32/30 - 3/30 = 1 29/30

p)5 5/13 - 3 1/2 = 5 10/26 - 3 13/26 = 4 36/26 - 3 13/26 = 1 23/26

Answer 2

a)=8/10+1/10=9/10

b)=1/6+4/6=5/6

c)=8/9-3/9=5/9

d)=13/10-2/10=11/10=1 1/10

e)=10/15+3/15=13/15

f) = 8/14+7/14=15/14=1 1/14

g)=12/5+7/2=24/10+35/10=59/10=5 9/10

h) =31/7+8/3=93/21+56/21=149/21=7 2/21

i) =12/15-10/15=2/15

j) =20/28-7/28=13/28

k) =19/8-7/6=114/48-56/48=58/48=1 10/48= 1 5/24

l) =9/2- 15/5=45/10-30/10=15/10=3/2=1 1/2

m)=9/4-8/3=27/12-28/12=-1/12

n)=46/9-11/6=276/54-99/54=177/54=3 5/18

o)=31/15-1/10=41/150-16/150=25/150=1/6

p)=85/13-7/2=170/26-91/26=79/26=3 1/26
