Question

How do you write a decimal that is of 1/10 or 3.0?

Answer 1

Assuming you meant `1/10` of `3.0`
the answer is `color(green)(0.3)`

Explanation:

The expression `a` of `b` when `a` is a fraction
means that we need to multiply: `a xx b`

In this case:
`color(white)("XXX")1/10xx3.0 =3/10=0.3`
