Paulo renamed 18 as a decimal. He knows the decimal equal to 1/4, and he knows that 1/8 is half as much as 1/4. Can you use ideas to show another way to find the decimal equal tom1/8?
Of course! One way to find the decimal equivalent of 1/8 is by dividing 1 by 8. Here's how you can do it:
To divide 1 by 8, you can use long division method. Write 1 as the dividend and 8 as the divisor:
```
0.125
-----------
8 | 1.000
- 8
------
20
- 16
----
40
- 40
----
0
```
As you can see, when dividing 1 by 8, you get a quotient of 0.125. So, the decimal equivalent of 1/8 is 0.125.
It's important to remember that when dividing, you can keep adding zeros after the decimal point as needed. Here, we added a zero after the decimal point to the dividend (1) to continue the division process.
