0.60=60100=60÷20100÷20
∵ H.C.F.(60,100) = 20
= 35
(b) 0.05
0.05=5100=5÷5100÷5
∵ H.C.F.(5,100) = 5
= 120
(c) 0.75
0.75=75100=75÷25100÷25
∵ H.C.F.(75,100) = 25
= 34
(d) 0.18
0.018=18100=18÷2100÷2
∵ H.C.F.(18,100) = 2
= 950
(e) 0.25
0.25=25100=125÷125100÷25
∵ H.C.F.(25,100) = 25
= 14
(f) 0.125
0.125=1251000=125÷1251000÷125
∵ H.C.F.(125,1000) =125
= 18
