What is 3/8 as a decimal?
The subject is “3/8 as a decimal”. We'll go step by step. There will be clear methods. Let's get into it.
The easiest way is direct division. What's that? It's simple. You divide 3 by 8. Just like that.
Use a calculator. Input 3 divided by 8. What do you get? That's right. It's .375. This is 3/8 of a decimal.
Multiply by 1
Wait! There's another way. You can multiply by 1. What do I mean? Keep reading.
Change 8 to 1000. That means you multiply 8 by 125. You also multiply 3 by 125.
What do you get? You get 375/1000. And that, my friend, is .375.
Using Place Values
Another way is using place values. Here's how.
- Start with 3/8. Multiply top and bottom by 125. Now, you have 375/1000.
- You see 375 in the numerator. Each digit is a place value.
- In decimals, 3 is in the tenths place. 7 is in the hundredths. 5 is in the thousandths.
Put it all together. You get .375. It's as simple as that.
The final way is repeated addition. You know how to add, right?
Take .1, that's 1/10. Add it to .2, that's 2/10. You get .3. Then, add .075, that's 75/1000. The total? Yes, .375.
