How to make divisions with decimals step by step
The quick method to make divisions with decimal numbers is a very easy trick. Remove the decimal point from the division and then replace the point in the answer. Although it may seem very complicated at first glance, the truth is that with this trick sure it will be very simple. So do not wait any longer and discover how to make divisions with decimals step by step.
Divide a decimal number by a whole number
You use a common division forgetting the decimal point. And then you put the decimal number in the same place as the dividend (the number that is divided). Look at this example:
- Split 9.1 in 7
You take the decimal point to 9.1 and the division is now: 91 ÷ 7
You already have an easier division. The result is 13.
But you have to reposition the decimal number to the result. 13 is now 1.3
How to divide by a decimal number
But why are you going to divide by a decimal number?
The trick is to convert the number you're dividing by a whole number. This exercise is solved by moving the decimal point of both numbers to the right. Example:
- Divide 6, 625 into 0, 53
Move the decimal point two spaces, or the number of spaces needed to have a whole number.
Now you are dividing by a whole number and you can continue as normal: 662.5 ÷ 53
This is a very safe method if you remember to move the decimal point the same number of places in both numbers.
This is another example:
- Divide 5.39 to 1.1
At this time you are not dividing by a whole number, so you need to move a decimal point. Move a space and you have now: 53, 9 ÷ 11
The rest of the division is easy because as you learned at the beginning of this math class, to divide a decimal number by an integer you forget the decimal point and then you put it back in the result. Following with the example:
53.9 ÷ 11
539 ÷ 11
049
The result is 4.9
