Answer 1

a). 0,5 - 1/3 =1/2-1/3=3/6-2/6=1/6

b).5/6 - 0,125 =5/6-1/8=20/24-3/24=17/24

c) 0,8 - 2/5 =0,8-40/100=0,8-0,4=0,4

D) 1,5 - 7/8 =3/2-7/8=12/8-7/8=5/8

e) 18,2 - 1/4 =18,2-0,25=17,95

f) 2i 2/7 - 0,6 =16/7-6/10=160/70-42/70=118/70=59/35=1 i 24/35

g) 4i 5/9 - 3,75 =41/9-15/4=164/36-145/36=19/36

h) 12,05 - 3i 1/8 =12,05-3,125=8,925

i) 4,7 - 1i5/6=47/10-11/6=282/60-110/60=172/60=2 i 13/15

Answer 2

       a)       0,5 - 1/3 = 5/10 – 1/3 = 15/30 – 10/30 = 5/30 = 1/6

       b)       5/6 - 0,125 =5000/6000 – 750/6000 = 4250/6000 = 17/24

       c)        0,8 - 2/5 = 8/10 – 2/5 = 8/10 – 4/10 = 4/10 = 2/5

       d)       1,5 - 7/8 = 1 1/2 – 7/8 = 1 4/8 – 7/8 = 12/8 – 7/8 =5/8                   e)    18,2 - 1/4 = 18,2 – 0,25 = 17,95                                                       f) 2i 2/7 - 0,6 = 2 2/7 – 6/10 = 2 20/70 – 42/70 = 160/70 – 42/70 = 118/70 = 1 48/70 = 1 24/35

g) 4 5/9 - 3 75/100 = 4 500/900 - 3 675/900 = 4100/900 - 3375/900 = 725/900 = 145/180 = 29/36

         h) 12 5/100 - 3 1/8 = 12 40/800 - 3 100/800 = 9640/800 - 2500/800 = 7140/800 = 714/80 = 8 74/80 = 8 37/40

          i) 4,7 - 1i5/6  = 4 42/60 - 1 50/60 = 282/60 - 110/60 = 172/60 = 2 52/60 = 2 26/30 = 2 13/15
