Ans. 9 8 7.4 9 8 7.4 Since there is 1 decimal place 3 9 4 9 6 in the multiplicand and 1 in the 6 9118 multiplier, there are 1 + 1 = 2 7 8 9 9 2 decimal places in the first 8886 6 product. 974958.76 9 8 7.4 Since there are 2 decimal 389983504 places in the multiplicand and 682471132 one in the multiplier, there are 779967008 2+1 = 3 decimal places in the 877462884 final product. 962674279.624 {c) .005' = .005 X .005 X .005 = .000000125. Ans. Since there are 3 decimal places in the multiplicand and 3 in the multiplier, there are 3 + 3 = 6 decimal places in the .vvo first product; but, as there are only 2 figures in the product, we prefix four ciphers to make the six decimal places. .000 02 5 Since there are six decimal places in .0 5 the multiplicand and 3 in the multi- 000000 125 plier, there are 6 + 3 = 9 decimal places in the final product. In this case we prefix six ciphers to form the nine decimal places.
