Question

How do you write 1.5 as a mixed number?

Answer 1

`1 1/2`

Explanation:

`1.5` is the same thing as "one and five-tenths," or "one and five over ten, or one and half," which is written as `1 1/2` as a fraction.

Answer 2

See another approach below:

Explanation:

You can multiply 1.5 by a form of 1 to build and improper fraction while not changing the value:

`1.5 = 1.5/1 = 10/10 xx 1.5/1 = (10 xx 1.5)/(10 xx 1) = 15/10`

We can now reduce this as:

`15/10 = (5 xx 3)/(5 xx 2) = (color(red)(cancel(color(black)(5))) xx 3)/(color(red)(cancel(color(black)(5))) xx 2) = 3/2`

If necessary, we can convert the improper fraction to a mixed number as:

`3/2 = (2 + 1)/2 = 2/2 + 1/2 = 1 + 1/2 = 1 1/2`
