# Dividing decimals

We'll start with simple problems like 3 / 2 and build to more complex problems like 4.5 / 0.15.

In this article, you'll learn how to divide decimals by jumping in and giving it a try without being shown how to do it first.

The problems go from easier to more difficult. Along the way there are examples and explanations to help you out if you get stuck. If you get a little confused, just think of it as a chance to learn!

Let's start by dividing whole numbers to get a decimal.

### Problem set 1:

Beautiful, let's move on to dividing larger whole numbers.

### Problem set 2:

Great, now we'll work on dividing a decimal by a whole number.

### Problem set 3:

Nice! Let's move onto working with slightly bigger numbers.

### Problem set 4:

Sweet! Next up are even bigger numbers!

### Problem set 5:

Baller. Now we'll divide decimals by decimals.

### Problem set 6:

Awesome! Let's try a few that are a bit harder.

### Problem set 7:

Great, we'll finish with a few more challenging problems.

### Problem set 8:

- I absolutely love how everyone is so helpful! But I have one question how would I divide 4.85 divided by 12.67 please help thanks :)(9 votes)
- It's impossible because 12.67 needs to be divided by 4.85. I hope This kinda helped. :)(3 votes)

- Wait there are more than 3 problems?!(7 votes)
- unforcenatlly yes(3 votes)

- Wait, 12 divided by 0.1 is 120? Thanks.(5 votes)
- Note that 0.1 is 1/10, and dividing by 1/10 is the same as multiplying by 10.

So 12 divided by 0.1 = 12 divided by (1/10) = 12*10 = 120.

Note that 120 answers the question "how many tenths are in 12?".

If the 120 still doesn't make sense to you, check this division by multiplication: 120*0.1 = 12.0 = 12, so it does check.(3 votes)

- can anyone break down how to do set 7, it was pretty confusing(0 votes)
- The first thing that you can do is shift the decimal in 4.5. When doing this, you also have to shift the decimal in 0.1. This is essentially 45/1, which is 45. So the answer is 45.(2 votes)

- is there a better way to divide whole numbers by decimals?(3 votes)
- One way to divide a whole number by a decimal is to first ignore the decimal point, divide the whole numbers, and in the end go as many places to the
**right**as there are places in the decimal. Going to the right makes sense, because (for positive numbers) dividing by a**smaller**number gives a**larger**answer.

Example: let's do 6 divided by 0.03. We can first do 6 divided by 3 to get 2. Then because 0.03 has two decimal places, we can go two decimal places to the**right**to get a final answer of 200.(4 votes)

- why are some some of these easy and complicate and try to trick you(3 votes)
- So that you can understand the subject more thoroughly. :D(3 votes)

- good

i go pay 100 for a bad teacher when here it is a free good site(4 votes) - I'm going to be a 5th grader so I'm doing 5th grader math to get ready for 5th grader but I didn't know it was this hard...(2 votes)
- Well it's not that hard when you have someone helping you an this will only get really confusing when you get in early middle school or late 5th grade........ I guess.(3 votes)

- why do we do this we still have paper sheet homework(2 votes)
