Question

What is 0.5 as a fraction?

Answer 1

`0.5= 1/2`

Explanation:

`0.5 = 0xx10^0 + 5xx10^(-1)`

`color(white)("XXX")=0xx10^0 + 5/10`

`color(white)("XXX")=5/10`

`color(white)("XXX")=1/2`

Answer 2

`0.5=1/2`

Explanation:

1. 0.5 is said as "five-tenths". This is because it is one place after the decimal (which is the tenths place).
2. It would then become five-tenths, written as: `5/10`
3. You would then simplify the faction: `5/10=1/2`
4. This is because five can go into itself once and goes into ten twice.
5. Another way of thinking about it is that five is exactly half of ten.
6. More mathematically, `5/10=5/(5xx2)=5/5xx1/2=1xx1/2=1/2`
