0.2 x 0.1 = Step 1: We can think of the 2 decimals as 2 numbers and we get the following:0.2 x 0.1 02 0 00 0.02 Note: When two decimals are multiplied, the decimal places in the result is the sum of the
decimal places in each decimal. In this question, each decimal has one decimal place so the sum is
2 decimal places.Step 2: As a proof of our answer we can say:0.2 = 20/100 AND 0.1 = 10/100 then:0.2 x 0.1 = 20 x 10 = 20 x 10 = 200 =
200/100 = 2 = 0.02100 100 100 x 100 10000 10000/100 100 Step 3: The answer can also be written as:0.02 = .02 = 2/100 = 2% Conclusion: We started out with two decimals and now have a new decimal.0.2 x 0.1 = 0.02 Close Window |
