Multiply the whole number by the denominator, then add the result to the numerator to get the new numerator (e.g., 2 2/3 = 8/3). Place the decimal point in the quotient above the decimal point in the dividend: Divide, being careful to line up the quotient properly: Remember to insert a placeholding zero in the quotient so that the decimal point ends up in the correct place. For example, 24.15 is a decimal number in which 24 is the whole number part and 15 is the fractional part. Divide the problem as usual. So, 1 divided by 2 would equal one half (1/2). To learn how to convert fractions to decimals using power of 10 denominators, keep reading! You can do this in your head, by using a calculator, or by doing long division. For example, if we need to divide 8934.5 1000, then it can be easily done by shifting the decimal point to the left and the answer will be 8.9345, Step 1: First, we will convert the divisor to a whole number 0.09 100 = 9, Step 2: Then, the dividend will also be multiplied with 100: 1.683 100 = 168.3. After this step, we can divide 789.1 37 using long division and we get the quotient as 21.32.

At the same time, move the decimal point in the dividend (9.345) two places to the right. 11.44. Step 3: After this step we will divide the numbers in the following way. At the same time, move the decimal point in the dividend (6.7) one place to the right:
\r\n\r\n
The problem asks you to round the quotient to one decimal place, so fill out the dividend with trailing zeros to two decimal places:
\r\n\r\n
Now youre ready to divide:
\r\n\r\n
