How do you divid whole numbers by decimals?
-decimals in general?
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 20/0.5 we need to move one position to the right.
275/3.14 (we need to move the decimal 2 position to the right)
