Find: (i)  \[1.3\times 10=13.0\]              (ii) \[\text{36}.\text{8}\times \text{1}0\]              (iii) \[\text{153}.\text{7}\times \text{1}0\]                  (iv) \[\text{168}.0\text{7}\times \text{1}0\] (v) \[\text{31}.\text{1}\times \text{1}00\]           (vi) \[\text{156}.\text{1}\times \text{1}00\]       (vii) \[\text{3}.\text{62}\times \text{1}00\]                  (viii) \[\text{43}.0\text{7}\times \text{1}00\] (ix) \[0.\text{5}\times \text{1}0\]             (x) \[~0.0\text{8}\times \text{1}0\]                         (xi) \[~0.\text{9}\times \text{1}00\]               (xii) \[0.0\text{3}\times \text{1}000\]

Answer:

                (i) \[\text{1}.\text{3}\times \text{1}0=\text{13}.0\]         (ii) \[\text{36}.\text{8}\times \text{1}0=\text{368}.0\] (iii) \[\text{153}.\text{7}\times \text{1}0=\text{1537}.0\] (iv) \[\text{168}.0\text{7}\times \text{1}0=\text{168}0.\text{7}0\] (v) \[\text{31}.\text{1}\times \text{1}00=\text{311}0.0\] (vi) \[\text{156}.\text{1}\times \text{1}00=\text{1561}0.0\] (vii) \[\text{3}.\text{62}\times \text{1}00=\text{362}.00\] (viii) \[\text{43}.0\text{7}\times \text{1}00=\text{43}0\text{7}.00\] (ix) \[0.\text{5}\times \text{1}0=\text{5}.0\] (x) \[0.0\text{8}\times \text{1}0=0.\text{8}0\] (xi) \[0.\text{9}\times \text{1}00=\text{9}0.0\] (xii) \[0.0\text{3}\times \text{1}000=\text{3}0.0.\]
