Question

Find the product :
(1) 35.853 × 100
(2) 3.14 × 17
(3) 1.07 × 0.02

Answer 1

(1) Given 35.853 × 100
Here we have to do normal multiplication with shifting the decimal point by two places to the right
Therefore 35.853 × 100 = 3585.3.

(2) Given 3.14 × 17
First, multiply as usual without looking at the decimal point
314 × 17 = 5338
Now mark the decimal point in the product to have one place of decimal as there in the given decimal
3.14 × 17 = 53.38.

(3) Given 1.07 × 0.02
First multiply as usual without looking at the decimal point
107 × 002 = 00214
Sum of the decimals points is 4
Now mark the decimal point in the product to have four places of decimal as there in the given decimal.
1.07 × 0.02 = 0.0214.
