Answer 1

a) 1,7+ 3/4=1 7/10 + 3/4 =1 14/20 + 15/20 = 1 19/20

b)1,8+1 8/13=  1 4/5 + 1 8/13 = 1 52/65 + 1 40/65 = 2 92/65 = 3 27/65

c)5 1/4+3,2= 5 1/4 + 3 1/5 = 5 5/20 + 3 4/20 = 8 9/20

d)6 1/8 – 2,75= 6 1/8 - 2 3/4 = 6 1/8 - 2 6/8 = 5 9/8 - 2 6/8 = 3 3/8

e) 2 1/3- 1,3= 2 1/3 - 1 3/10 = 2 10/30 - 1 9/30 = 1 1/30

f)1/3 - 0,1= 1/3 - 1/10 = 10/30 - 3/30 = 7/30

g)1/2 + 0,308 = 1/2 + 308/1000 = 500/1000 + 308/1000 = 808/1000 = 101 /125

h) 2,71 - 2/5 = 2 71/100 - 2/5 = 2 71/100 - 40 / 100 = 2 51/100
