Dividing decimals is a lot like dividing by a whole number. There is just one thing you need to remember before dividing: You have to make the number outside the house (divisor) a whole number (A number without a decimal).
It’s simple, move the decimal to the right until it is at the end of the number. Here’s the problem: 1.1 ) 6.3
Move the decimal to the right until you are at the end of the number. In this case, we only had to move it once. 1.1 ) 6.3 Since we moved the decimal on the divisor (# outside the house) we HAVE TO move the decimal in the dividend the same number of times. In this case it would also be one time.
What happens if we have a decimal in the divisor and not the dividend? 2.14 ) 797
Just remember, the dividend is a whole number so there is a decimal at the end of the dividend that is not there. 2.14 ) 797. The decimal would go here since the number is whole. You would still have to move it two places to the right. Is really…
