Question

How do you write 3/4 as a decimal?

Answer 1

`3/4=0.75`

Explanation:

Divide `3` by `4` to get `0.75`

The division in this case is a bit tricky due to the fact that you have to divide something small `3` into something bigger `4`.

as you can see at the start we borrow a zero to make our `3` into a `30` but we have to "signal" this loan by adding a `0,` into the result; then we take another zero (in red) to form a `20` and finish our division.

Answer 2

Here is another method.

Explanation:

`3/4` can be converted to a fraction `x/100`.

How? In the denominator, `4xx\color(red)(25)=100`. So we do the same for the numerator:
`3/4\color(red)((xx25)/(xx25))=(3xx25)/100=\color(blue)(75)/100`

Dividing by 100 means you move the decimal point backwards two digit spaces. So from the numerator value `75.00` you move two back, and you have `0.7500` or `0.75`.

(the 0's are there so you can see the decimal point. They actually don't count)
