Question 7.
Write as fractions in lowest terms:
(a) 0.60
(b) 0.05
(c) 75
(d) 0.18
(e) 25
(f) 0.125.
Solution.
(a) 0.60
\(0.60 =\frac { 60 }{ 100 } =\frac { 60\div 20 }{ 100\div 20 } \)
∵ H.C.F.(60,100) = 20
= \(\frac { 3 }{ 5 } \)
(b) 0.05
\(0.05=\frac { 5 }{ 100 } =\frac { 5\div 5 }{ 100\div 5 } \)
∵ H.C.F.(5,100) = 5
= \(\frac { 1 }{ 20 } \)
(c) 0.75
\(0.75=\frac { 75 }{ 100 } =\frac { 75\div 25 }{ 100\div 25 } \)
∵ H.C.F.(75,100) = 25
= \(\frac { 3 }{ 4 } \)
(d) 0.18
\(0.018 =\frac {18 }{ 100 } =\frac { 18\div 2 }{ 100\div 2 } \)
∵ H.C.F.(18,100) = 2
= \(\frac { 9 }{ 50 } \)
(e) 0.25
\(0.25 =\frac { 25 }{ 100 } =\frac { 125\div 125 }{ 100\div 25 } \)
∵ H.C.F.(25,100) = 25
= \(\frac { 1 }{ 4 } \)
(f) 0.125
\(0.125 =\frac { 125 }{ 1000 } =\frac { 125\div 125 }{ 1000\div 125 } \)
∵ H.C.F.(125,1000) =125
= \(\frac { 1 }{ 8 } \)
