Question

I need to know which of these are rational numbers.

Answer 1

For a number to be rational, it must be able to be expressed as a fraction of two integers, from the list in the question, the rational numbers are:

`1.25=(125)/(100)`
`23.5\bar{20}=(23285)/(990)`

`(20)/(23)`
`\sqrt[]{0.04}=0.2=(1)/(5)`
`-88=(-88)/(1)`
