How to multiply and divide decimals(all positive numbers)

How to multiply and divide decimals(all positive numbers) By Samuel Santiago, Shelby Daniel , Naomi Awodumila

Step-by-step Multiply the equation normally. 2.13 x 0.3 0639

How to multiply Multiply normally ignoring the decimals THEN put the decimal point in the answer(the answer will have as many decimal places as the 2 original numbers combined) In other words, just count up how many numbers are after the decimal point in both the numbers you are multiplying, then the answer should have that many numbers after the decimal point.

Step-by-step Start with your equation. 0.3 x 2.13

Step-by-step Count the number of decimal points. Decimals 2.13 2 x 0.3 +1 0639 3

Step-by-step Since there are three numbers after the decimal point, you would put the decimal point three places from the right. 2.13 x 0.3 0.639

How to divide Use division or long division(ignoring the decimals) After solving put the decimal point in the same spot as the dividend(the number being divided)

Step-by-step Start with your equation. 14.8 4

Step-by-step Divide the equation normally. 3 7 4 14.8 -12 28 -28 0

Step-by-step As you did with multiplication, count up how many numbers are after the decimal point. 3 7 decimals 4 14.8 1 -12 28 -28 0

Step-by-step Put the decimal in one space from the left. Your final answer is 3.7. 14.8 4 = 3.7
