Find: (i) \[\text{4}.\text{8}\div \text{1}0\]                                       (ii) \[\text{52}.\text{5}\div \text{1}0\]          (iii) \[0.\text{7}\div \text{1}0\]                  (iv) \[\text{33}.\text{1}\div \text{1}0\] (v) \[\text{272}.\text{23}\div \text{1}0\]              (vi) \[0.\text{56}\div \text{1}0\]        (vii) \[\text{3}.\text{97}\div \text{1}0\]

Answer:

                (i) \[4.8\div 10=\frac{4.8}{10}=\frac{4.8}{10.0}=\frac{48}{100}=\frac{48\div 4}{100\div 4}\]\[=\frac{12}{25}=0.48\] (ii) \[52.5\div 10=\frac{52.5}{10}=\frac{52.5}{10.0}=\frac{525}{100}=\frac{525\div 25}{100\div 25}\]\[=\frac{21}{4}=5\frac{1}{4}=5.25\] (iii) \[0.7\div 10=\frac{0.7}{10}=\frac{0.7}{10.0}=\frac{7}{100}=0.07\] (iv) \[33.1\div 10=3.31\] (v) \[272.23\div 10=27.223\] (vi) \[0.56\div 10=0.056\] (vii) \[3.97\div 10=0.397\].
