Find: (i) \[\text{2}.\text{5}\times 0.\text{3}\]                (ii) \[0.\text{1}\times \text{51}.\text{7}\]          (iii) \[0.\text{2}\times \text{316}.\text{8}\]        (iv) \[\text{1}.\text{3}\times \text{3}\text{.1}\] (v) \[0.\text{5}\times 0.0\text{5}\]         (vi) \[\text{11}.\text{2}\times 0.\text{15}\]        (vii) \[~\text{1}.0\text{7}\times 0.0\text{2}\]                     (viii) \[\text{1}0.0\text{5}\times \text{1}.0\text{5}\] (ix) \[\text{1}0\text{1}.0\text{1}\times 0.0\text{1}\]      (x) \[\text{1}00.0\text{1}\times \text{1}.\text{1}\]

Answer:

                (i) \[\text{2}.\text{5}\times 0.\text{3}=0.\text{75}\]       (ii) \[0.\text{1}\times \text{51}.\text{7}=\text{5}.\text{17}\] (iii) \[0.\text{2}\times \text{316}.\text{8}=\text{63}.\text{36}\] (iv) \[\text{1}.\text{3}\times \text{3}.\text{1}=\text{4}.0\text{3}\] (v) \[0.\text{5}\times 0.0\text{5}=0.0\text{25}\]               (vi) \[\text{11}.\text{2}\times 0.\text{15}=\text{1}.\text{68}0\] (vii) \[~\text{1}.0\text{7}\times 0.0\text{2}=0.0\text{214}\] (viii) \[\text{1}0.0\text{5}\times \text{1}.0\text{5}=\text{1}0.\text{5525}\] (ix) \[101.01\times 0.01=1.0101\] (x) \[100.01\times 1.1=110.011\]
