Why do you move the decimal to divide a decimal by a decimal?
To move the decimal you must move the decimal in the divisor all the way to the right to make it a whole number. Then in the dividend, you move that decimal to the right the same amount of spaces you did in the divisor.
How do get rate when only given is base and percentage?
you can divide it BASE is the dividend and the Percentage as the divisor when you get an answer that has a decimal point move it two times to the right and replace it with a percent sing
What do you do when there is a decimal on the outside of division house?
To divide decimal numbers:If the divisor is not a whole number, move decimal point to right to make it a whole number and move decimal point in dividend the same number of places.Divide as usual. ...Put decimal point directly above decimal point in the dividend.Check your answer.
How do you divid 00.5 diviser by 00.57?
To divide by a decimal, make the divisor a whole number by moving the decimal point to the right; the dividend must also be changed by moving its decimal point the same number of digits to the right. So to divide 0.5 by 0.57, make the divisor 0.57 into 57 by moving the decimal point two digits to the right, then also move the decimal point of the dividend (0.5) two places to the right to give 50. Thus: 0.5 / 0.57 = 50 / 57 ~= 0.88
If the divisor in a division problem 2.25 how many places should you move the decimal point in the dividend?
If the dividend is between 2.25*10k and 10k+1 where k is any integer, then the decimal point does not move while if the dividend is between 10k and 2.25*10k then the decimal point moves 1 place to the left.

How many places should you move the decimal point in the dividend if the divisor is 0.000000009?
It is moved 9 places.

When dividing decimals the divisor must always be a?
The divisor must always be a whole number. If it is not already, then you must multiply both the the divisor and dividend by ten until the divisor is no longer a decimal. For example, let's say you have to divide 1.0/0.5 . The divisor in this case would be 0.5 . To multiply by ten, simply move the decimal over to the right one space. That would leave you with 5.0, but since you have to do it on both sides, the final expression would look like this: 10/5 .
How to divide manually in division if the divisor is higher in value than the dividend?
You add a decimal point and decimal digits. These must then also be added in the result. For example, to calculate 1 / 7, convert that to 1.0 / 7, and do the calculations for 10 / 7 (the answer starts with 1.4...). Then move the decimal point one to the left in the result: 0.14...
What can you divide by 100?
Any number can be divided by 100. Move the decimal point two places to the right.
Why can you move the decimal point in the divisor to th right as long as you move the decimal point in the dividend the same number of places to the right?
Moving a decimal point to the right is the same as multiplying a number by a power of ten. As long as both numbers are multiplied by the same amount, they will retain their same relationship.
What is an algorithm for dividing decimals and tell why the algorithm works?
Decimals are the equivalent of fractions. get rid of the decimal in the divisor by moving it to the right end of the number, count spaces moved and move the decimal in the dividend the same number of spaces (adding zeros if necessary). This works because to get an equivalent fraction you multiply the numerator (dividend) and the denominator (divisor) by the same number. Moving a decimal to the right is the same as multiplying by 10, 100, 1000, etc. if you move the decimal 1, 2, 3, etc. spaces so you are in effect multiplying both by these multiples of 10 by moving the decimal the same number of spaces. After this just follow the rules for division, divide an appropriate number of spaces, multiply, subtract, bring down, etc.
Why do you move the decimal point the same number of places in the dividend and the divisor?
That is because if you do the same thing to the divisor as the dividend then nothing changes. Say you have 2 divided by 4; if you multiply both by 10 you have 20/40 which is the same thing. So if you have 2.36 divided by 4.19 that is the same as 236/419 since you multiplied both by 100.
