∙53×10=53.0×10––––––––––––––––––––––
We know multiplication of 53.0 by 10 moves the decimal point 1 unit to the right.
∴53×10=53.0×10=530.0=530
∙530÷10=530.0÷10––––––––––––––––––––––––
We know division of 530.0 by 10 moves the decimal point 1 unit to the left.
∴530÷10=530.0÷10=53.00=53
∙23×104=23.0×104––––––––––––––––––––––––
We know multiplication of 23.0 by 104 moves the decimal point 4 units to the right.
Hence,
23×104
=23.0×104
=230,000.0
=230,000
∙470,000÷103=470,000.0÷103––––––––––––––––––––––––––––––––––––
We know division of 470,000.0 by 103 moves the decimal point 3 units to the left.
Hence,
470,000÷103
=470,000.0÷103
=470.0000
=470
