Question

A farmer can plant 4/5 of an acre in 2/3 hour how many acres can he plant in 1 hour

Answer 1

6/5 of an acre, or 1 1/5.

Answer 2

Portion of acre planted by farmer =
`(4)/(5)`

Time required by the farmer to plant the above portion =
`(2)/(3)`

In
`(2)/(3)` hours the farmer planted
`(4)/(5)` acre

So in 1 hour the farmer can plant =
`(4)/(5)/ (2)/(3)`

=
`(4)/(5)* (3)/(2)`

=
`(12)/(10)`

Portion of acre planted by the farmer in 1 hour =
`(12)/(10)` acre
