how to divide decimals in your head

Write the problem as usual:

You need to move the decimal point in the divisor (0.021) three places to the right, so attach an additional trailing zero to the dividend (3.15) to extend it to three decimal places:

Now you can move both decimal points three places to the right. Here's how to divide decimals step by step: Move the decimal point in the divisor and dividend. While dividing decimal numbers, we need to follow a certain set of rules but the basic process of division remains the same. At the same time, move the decimal point in the dividend (9.345) two places to the right. Instead, attach enough trailing zeros to round the quotient to a certain number of decimal places. For example, .5 x 100 = 50%. Place a decimal point in the quotient (the answer) directly above where the decimal point now appears in the dividend. At the same time, move the decimal point in the dividend (6.7) one place to the right:

The problem asks you to round the quotient to one decimal place, so fill out the dividend with trailing zeros to two decimal places:

Now youre ready to divide:

Round the quotient to one decimal place:

9.13 / 4.25 = 2.15. As a small thank you, wed like to offer you a $30 gift card (valid at GoNift.com). First, write the problem as usual:

\r\n\r\n

Turn the divisor (4.25) into a whole number by moving the decimal point two places to the right. Let us understand this with a simple example. In this case, 0.0020 has 4 numbers after the decimal and 0.005 has 3 numbers after the decimal. Are the last two digits in your number divisible by 4? Step 3: After this step we will divide the numbers in the following way. Find out how many times 4 will go into 6 (the first digit of the dividend).
