Consequently, how do you divide a decimal number by another decimal?

To divide a decimal by another decimal:

  1. Move the decimal point in the divisor to the right until it is a whole number.
  2. Move the decimal point in the dividend to the right by the same number of places as the decimal point was moved to make the divisor a whole number.
  3. Then divide the new dividend by the new divisor.

Also, how do we multiply decimals? Multiply the numbers just as if they were whole numbers.
  1. Line up the numbers on the right - do not align the decimal points.
  2. Starting on the right, multiply each digit in the top number by each digit in the bottom number, just as with whole numbers.
  3. Add the products.

Just so, how do I divide fractions?

In order, the steps are:

  1. Leave the first fraction in the equation alone.
  2. Turn the division sign into a multiplication sign.
  3. Flip the second fraction over (find its reciprocal).
  4. Multiply the numerators (top numbers) of the two fractions together.
  5. Multiply the denominators (bottom numbers) of the two fractions together.

How do you divide decimals when the divisor is bigger?

Perform the division.

  1. Remember to place a zero in the quotient when the divisor is larger than the dividend.
  2. Place the decimal point in your quotient.
  3. Check your answer: Multiply the divisor by the quotient to see if you get the dividend.
