I need help on Q.19 please

Answer 1

This is simple.

=
`3(3)/(5)` ÷
`4(1)/(2)`
change the mixed fractions to improper ones.

`(18)/(5)` ÷
`(9)/(2)`
Multiply
`(18)/(5)` by the reciprocal of
`(9)/(2)` which is
`(2)/(9)`

=
`(18)/(5)` ×
`(2)/(9)`
=
`(36)/(45)`

Since it can be simplified further, we get the answer

`(4)/(5)`

How?
There is a common multiple 9

`(36/9)/(45/9)`
=
`(4)/(5)`
Answer= B.
`(4)/(5)`
