Answer 1

Solutions :-

1.
`(1)/(5) - (1)/(3)`

`= (3 - 5)/(15)`

`= ( - 2)/(15)`

2.
`- 3 + (1)/(3)`

`= ( - 9 + 1)/(3)`

`= ( - 8)/(3)`

_______________________

3.
`( - 3)( (1)/(3) )`

`= - 3 * (1)/(3)`

(By cancelation)

`= - 1`

_______________________

4.
`( - 3) / ( (1)/(3) )`

`= - 3 / (1)/(3)`

`= - 3 * (3)/(1)`

`= ( - 9)/(1)`

`= - 9`

_______________________

5.
`{25}^(2)`

`= 25 * 25`

`= 625`
