Solution.--Multiply as in simple numbers, 2149 2.1 4 9 by 634. 6.3 4 There are three decimal orders in 2.149, and two 8 5 9 6 decimal orders in 6.34; hence, there must be five 64 4 7 decimal orders in the product (Art. 146). There-1 2 8 9 4 fore, the product is 13.62466.!3.6 2 4 6 6 2. Multiply.0276 by.035. Solution.--Multiply the numerator (Art. 134, 6) 276 by the numerator 35; the result is 9660. There are four decimal orders in.0276, and three decimal orders in.035; hence, there must be seven decimal orders in the product (Art. 146); three ciphers, then, must be prefixed to 9660. Therefore, omitting the.0009660 cipher on the right (Art. 140,2) the product is.000966. 3. Multiply 2.075 by 100. Solution.--Write 2075 and place the decimal Opkration. point between 7 and 5, two places farther to the right 2 0 7.5 than it is in 2.075. Rem.--To multiply 207.5 by 100, annex a cipher and mcve the decimal point two places to the right. Rule.--1. Multiply together the numerators of the decimals as in Simple Numbers. 2. Point off as many decimal orders in the product as there are decimal orders in both factors. Rem. 1.--When the number of figures in the product of the numerators is less than the number of decimal orders required, prefix ciphers. (Ex. 2.) Rem. 2.--After placing the decimal point, omit ciphers at the right of the decimal part of the product. (Ex. 2.) Rem. 3.--To multiply a decimal by 10, 100, 1000, etc., remove the decimal point as many places to the right as there are ciphers in the multiplier. If there be not enough figures annex ciphers. 23. Multiply.0001 by 100..01 24. Multiply 1 tenth by 1 hundredth..001 25. Multiply 1 hundred by 1 ten-thousandth..01 26. Multiply 43 thousandths by 21 ten-thousandths..000090a 27. ...
