...explanations given in Lesson XII., that to multiply a decimal by any power of 10, we need only move the decimal point as many places to the right as there are ciphers in the multiplier. For example : — •31567 x 100 is 31-567. For -34567 x 100 •= AVoVs...

...instances we get the following rule:—To multiply a decimal fraction by a decimal number (106), move the decimal point as many places to the right as there are ciphers in the decimal number. When this cannot be done, add ciphers to the right of the decimal (116)...

...Divide 0,8297592 by 0,153. Quo. 5,4232. 6. Divide 27 by 0,2639. Quo. 102,3114. NOTE. — To divide by 10, 100, 1000, &c., remove the decimal point as many places to the left as thece are O's in the divisor. Thus, 167,354 -*• 10 = 16,7354, 9217,3719 -s- 100 = 92,173719....
