How do you divid whole numbers by decimals?
EX: 20/0.5
-decimals in general?
Thank you!
You move the decimal point in the divisor to make it a whole number.
Example: 0.5 is 5.
Then you add one or more zeroes to the dividend. Move the decimal point over the same number of places that you did in the divisor.
Example: 20 = 200.
So -- 20 / 0.5 = 200 / 5 = 40
If it is not a recurring decimal, I would find out how many decimal places I need to move to the right on the denominator to make it an integer (whole number). Then I add the same number of zeroes on the numerator and divide by the integer.
For example:
for 20/0.5 we need to move one position to the right.
So
20/0.5
= 200/5
= 40
Try
275/3.14 (we need to move the decimal 2 position to the right)
275/3.14
=27500/314
=87 182/314
=87 91/157
To divide a whole number by a decimal, you can follow these steps:
Step 1: Convert the decimal into a whole number by moving the decimal point to the right until it becomes a whole number. Count the number of places you moved the decimal point.
For example, let's say we want to divide 20 by 0.5. Moving the decimal point of 0.5 one place to the right results in 5 (0.5 becomes 5).
Step 2: Divide the whole number by the new whole number obtained in step 1.
In this case, divide 20 by 5, which gives you the answer of 4.
So, 20 divided by 0.5 equals 4.
In general, when dividing a whole number by a decimal number, you can apply this method of converting the decimal into a whole number and then performing the division.
