When we divide a number by 10, shift the decimal point one step towards left, since which has only one zero.
(i) 4.810=0.48 [Shifted the decimal point one step towards left]
(ii) 52.510=5.25 [Shifted the decimal point one step towards left]
(iii) 0.710=0.07 [Shifted the decimal point one step towards left]
(iv) 33.110=3.31 [Shifted the decimal point one step towards left]
(v) 272.2310=27.223 [Shifted the decimal point one step towards left]
(vi) 0.5610=0.056 [Shifted the decimal point one step towards left]
(vii) 3.9710=0.397 [Shifted the decimal point one step towards left]
