Given:
`1(1)/(3) :2(1)/(3)`

To simplify this ratio, convert the mixed fractions into improper fractions:

`(4)/(3)` :
`(7)/(3)`

Then to divide ( because ratio = division ) turn around
`(7)/(3)` and multiply:

`(4)/(3) * (3)/(7)`

Then multiply:

`(12)/(21)`

Finally simplify this fraction by dividing the denominator & numerator by 3:

=
`(4)/(7)`
