Answer 1

a) 3,6 + 2/3 =3 6/10+2/3=36/10+2/3=108/30+20/30=128/30=4 8/30= 4 4/15

b) 4i1/8-1,11 = 33/8-111/100=825/200-222/200=603/200=3 3/200

c) 2,75+2/7 = 2 75/100+2/7=1925/700+200/700=1725/700=2 325/700

d) 0,125-1/9 = 125/1000-1/9 = 1125/9000 -1000/9000=125/9000=25/1800=5/360=1/72

e)3 i 1/3-3,3 =10/3-3 3/10=10/3-33/10=100/30-99/30=1/30

f)1i 1/5-0,09 =  6/5-9/100=180/100-9/100=171/100=1  71/100
