It involves the division in which decimal numbers are used. Now, let us learn how to divide decimals by decimals. Start by dividing the whole number part by the divisor. Find out how many times 4 will go into 6 (the first digit of the dividend). This can be done by multiplying the divisor by the powers of 10 and then accordingly multiplying the dividend also by the same power of 10. If you are trying to convert 1/5 to a fraction with a denominator of 10, you would multiply it by 2/2. You just look for a fraction with a power of 10 denominator (or one that can be readily made into one) and convert the top number into a decimal. Instead, attach enough trailing zeros to round the quotient to a certain number of decimal places. After you divide, you can check your work by multiplying the decimal by the denominator to get the numerator. Are the last two digits in your number divisible by 4? While multiplying decimals, we add the number of decimal places of the multiplicand and the multiplier and then place the decimal point in the product according to those number of places. Are there really 16 lots of 0.4 in 6.4? Take the last digit in a number. The total weight of all the marbles together is equal to 376 grams. We use cookies to make wikiHow great. Step 3: Divide and bring down the other digit in sequence. For example, if we need to divide 432.7 1000, then it can be easily done by shifting the decimal point to the left and the answer will be 0.4327. Dividing decimals by whole numbers is similar to normal division. Dividing Decimals is similar to dividing whole numbers, keeping in mind the position of the decimal point. Use it to try out great new products and services nationwide without paying full pricewine, food delivery, clothing and more. This one's not as easy. For example, if we need to divide 45.67 10, then it can be easily done by shifting the decimal point to the left and the answer will be 4.567, In order to divide a decimal number by 100, move the decimal point to the left by two places. For example: 0.0020 0.005 = 0.0000100. Then, perform regular division with the new numbers. [6] The fraction 2/3, for example, can also be stated as 2 divided by 3. [5] So if you moved the decimal 2 places to the right, it would be above the bar and right after the 0 below it. 1. So, put 1 in the quotient and write 4 below 6. Grace is currently a math instructor at the City College of San Francisco and was previously in the Math Department at Saint Louis University.
