Answer» (i) Given 3.14 × 17 First multiply as usual without looking at the decimal point 3.14 × 17 = 578 Now mark the decimal point in the product to have one place of decimal as there in the given decimal 3.14 × 17 = 57.8 (ii) Given 0.745 × 12 First multiply as usual without looking at the decimal point 0.745 × 12 = 894 Now mark the decimal point in the product to have three places of decimal as there in the given decimal 0.745 × 12 = 8.94 (iii) Given 28.73 × 47 First multiply as usual without looking at the decimal point 28.73 × 47 = 135031 Now mark the decimal point in the product to have two places of decimal as there in the given decimal 28.73 × 47 = 1350.31 (iv) Given 0.0415 × 59 First multiply as usual without looking at the decimal point 0.0415 × 59 = 24485 Now mark the decimal point in the product to have four places of decimal as there in the given decimal 0.0415 × 59 = 2.4485

Find the product:(i) 3.14 × 17(ii) 0.745 × 12(iii) 28.73 × 47(iv) 0.0415 × 59

Answer»

(i) Given 3.14 × 17

First multiply as usual without looking at the decimal point

3.14 × 17 = 578

Now mark the decimal point in the product to have one place of decimal as there in the given decimal

3.14 × 17 = 57.8

(ii) Given 0.745 × 12

First multiply as usual without looking at the decimal point

0.745 × 12 = 894

Now mark the decimal point in the product to have three places of decimal as there in the given decimal

0.745 × 12 = 8.94

(iii) Given 28.73 × 47

First multiply as usual without looking at the decimal point

28.73 × 47 = 135031

Now mark the decimal point in the product to have two places of decimal as there in the given decimal

28.73 × 47 = 1350.31

(iv) Given 0.0415 × 59

First multiply as usual without looking at the decimal point

0.0415 × 59 = 24485

Now mark the decimal point in the product to have four places of decimal as there in the given decimal

0.0415 × 59 = 2.4485
